60 fps lock in fullscreen setting after update?

January 2, 2017

The devs posted that there will be problems with fullscreen, until the NVIDIA profile has been updated to DX11 and i don't think that happened yet (could be wrong though).

So until then, you might have to stick to windowed mode.

I believe you're spot on. I just double checked my nvidia control panel settings, and they're set correctly. Some people say theirs are working fine but the OP is a 21:9 ultrawide, so is mine. There's an fps/refresh counter built into my monitor. When things are working normally that number matches a games fps counter if it's built in and not exceeding 100fps. if exceeding 100 fps the counter on the monitor stops at its highest achievable of 100hz but the games counter can potentially go beyond that just like using a 60hz monitor while running a system that gets more than 60fps with v-sync disabled.

This was working fine and dandy before the patch released prior to the OP's post. However now when I start the game in fullscreen mode my monitor resets..and switches to a max 60hz refresh rate. The ingame counter will still show higher than 60 if v-sync is off but my monitor at this point is not displaying 100hz refresh rate when il-2 launches in fullscreen.

For some reason when IL-2 BoS launches it completely resets the monitor as in black screen and click as if i just turned it on then i get the log in screen, I get an icon stating "DP" with a little display port icon and suddenly im capped at 60hz even when flying missions (which its almost always at 60 in the menus in full screen, then used to jump up when i started flight. I have tried lowering the fps limiter from 120 to 80 (why skip 100?) to no avail. However running the game in borderless does NOT reset the monitor. Seems to only happen in specifically il-2 BoS as of late. i'll try deleting the old il-2 profile alltogether but hopefully we'll get a fix soon.

Sorry for the delay in responding, Christmas and New Year got in the way.

Having tested with LOW GFX Preset I can confirm G-Sync is still working as intended in full-screen mode.

With V-Sync ON in the NVidia control panel, but OFF in-game, my FPS never exceeded 144. In-game FPS was fluctuating between 115 - 144 with no tearing.

With V-Sync set to FAST in the NVidia control panel, but OFF in-game, my FPS exceeded 144 on occasion. In-game FPS was fluctuating between approx 115 - 150 with no tearing.

In the interim, you can manually set your fps limiter in the data/startup.cfg file, (I have a 75hz monitor) to any value you want. If you change any settings in game though you'll have to go edit again manually, as the game will overwrite the file to 80 or 120.

For you it's working... for me and the OP on our 21:9 ultrawides it is NOT working. my refresh rate is being set to 60hz when I load at fullscreen, and a feature built into the monitor is letting me know that's the case.

Yeah I set it 100fps in the startup.cfg and it seems to be working in windowed mode..

unfortunately fullscreen wants to cap at 60hz refresh rate. When this the case, even if the game's FPS counter is reporting higher than 60hz the monitor isn't capable of displaying more than 60fps, which is what causes the tearing without v-sync. Mind you, i've played on more than one 60hz monitor with games running at a much higher fps with no visible tearing, but I think the end result is that the monitor was really only displaying 60fps as a hz is defined as one cycle per second, or there were simply frames I was not able to see due to the limitation of my monitor. It could be the case that "G-sync" is still functioning @ 60hz as I don't know the full extent of what g-sync does. So that might have been an incorrect statement on my part that "g-sync functionality seems broken"

A more specific explanation is that launching the game in fullscreen seems to be resetting my monitor from its overclock to 100hz refresh rate down to its normal 60hz. And when I look at the monitor's settings the screen overclock is still maxed out. This is ONLY happening in il-2 BoS and it wasn't happening prior to the update that released a day or two before the OP

Nifty feature on this monitor is it has a built in fps counter.. and with v-sync off launching il-2 full screen, regardless of whether the game is counting above 60fps, the max the monitor will display is 60fps or 60hz . The only other game I've played recently that won't allow a max of 100fps was a final fantasy game that was capped at 30fps. Otherwise (as with any other game) i get a 100 in the upper right hand corner that may lower from time to time if my system isn't outputting 100fps.

So, instead of checking your fps counters, check your refresh rates in full screen. If your monitor natively has a 144hz refresh rate I doubt you'll have the issue. But seeing as the 34" ultrawide g-sync monitors available now both require overclocking(a feature built into the montior menu) the refresh rate to a max of 100hz, the only thing I can say is they did something in the last patch that is forcing my monitor reset and run at a 60hz refresh rate in fullscreen. My monitor is still displaying at 100hz refresh rate in borderless.. but I can't say I'd mind if they figured out what in the last patch made it impossible to do so in full screen.

When I load fullscreen on my 21:9 UWHD, I also get locked at 60hz too.

Windowed mode addresses the 60hz issue and improves the performance; however, the framerate numbers you're seeing in the top right or external program are lies.

January 4, 2017

Same thing here: Locked at 60 fps at full screen regardless of monitor refresh rate and FPS limiter.

Do the devs take notice of these threads or do we have to report it to the sticky threads?

I'd have to assume the majority of BoS players aren't using 21:9 UWHD or monitors using an "overclock" feature for refresh rates and therefore this thread isn't a hot topic. I'm convinced this is only happening to freesync/g-sync users whose monitors have to be overclocked (albeit by software built into the monitor's OSD) to exceed 60hz. People with native 144hz refresh rates won't get the issue, as the game resetting the monitor wouldn't cause the native refresh rate to change.

I will say I tend to see devs and producers respond to people more in the Dev Diaries from what I've seen but I haven't really spent a large amount of time on the forums.

I recently brought up another issue in the Dev Diary for the latest patch and one of the threads regarding that issue actually got a response from a producer, so hopefully that will be getting a fix very soon.

I have been playing in windowed mode and made sure g-sync is set to work in windowed mode as well as full screen.

The numbers at the top right of my screen aren't a lie. I generally average 85-100 fps in IL-2 BOS with the limiter set to 100 in startup cfg. My system can run it at higher frames per second, but my monitor won't refresh fast enough to show more than 100 fps. G-sync syncs my monitors refresh rate with the fps the game is running at IF it's under the maximum refresh rate, and my refresh rate is being shown by the monitor itself becuase Acer Predators are cool like that. I literally watch my screen's refresh rate change with fps dips (or switching from windowed to full screen in IL-2)

I will say the game seems to be running fine at 100hz in windowed mode other than a problem related to FFB sticks. In nvidia control panel allow g-sync to work with programs running in windowed mode for results. While I would love to see full screen functionality returned to us oddballs who went with an expensive single monitor with less screen retail than 3 smaller monitors (and perfectly happy with it as I LOVE MY MONITOR) in the near future, I see no need to be impatient with the devs right now. They seem to be doing a lot of work and keeping us updated with dev diaries and even responding to peoples concerns in those threads. I'm sure if you mention this thread in the latest dev diary someone will take a look at it at some point. Hopefully it's not a difficult fix for them. To anyone who takes that advice...be nice about it, I'm sure courtesy nets better results.

EDIT: Forget this post. I was accidentally using Windowed mode and thought I was using Full screen.

~~OK... I was able to solve this issue for myself. I can now use Full screen and it is smooth. Here are my observations about the full screen mode:~~

~~-Full screen mode is locked at 60 fps IF you have V-sync enabled in the game or in Nvidia Control panel (or in both).~~

-I'm using G-sync Ultrawide monitor with 100Hz refresh rate. I disabled V-sync in game and from Nvidia Control panel. G-Sync is enabled. My fps counter showed 120-140 fps but it was very jerky and felt like having 20 fps.

-The solution for me was to disable V-sync in game, disable V-sync in Nvidia control panel and set fps limiter so that it doesn't exceed your monitors refresh rate (I have "fps_limit = 99" in startup.cfg). My understanding is that G-sync doesn't work if your fps is above your refresh rate and that's why I was getting stutters and jerky movement with high fps.

~~So it seems the bug is related to how V-Sync works in full screen mode. Players with 60Hz monitors will not notice this.~~

Try fast sync forced via control panel (Nvidia)

i have no fps locks only on the menu screen where it does not matter

WOW thats a hot CPU for just gaming load. ?? 63*C :O
Be lucky if i can get mine to reach 45*C After 5 hours of Cinebench loops on 8 cores loaded.

It's not the FPS that gets locked, its the monitor's refresh rate that gets changed. please confirm if your monitor is running at 100hz refresh in fullscreen? (not the fps counter in game)

Oh no... I made a mistake of accidentally using windowed mode and thought I was using Full screen. So nothing is fixed.

Yes, you're correct. Monitor refresh rate drops to 60Hz when in Full screen mode.

thanks. in the meantime just be sure nvidia control panel is set to allow g-sync in windowed mode and running in borderless should be fine.

People with native 144hz refresh rates won't get the issue, as the game resetting the monitor wouldn't cause the native refresh rate to change.

My monitor has a native refresh rate of 144hz (Benq XL2730Z 2560x1440p 144hz freesync) and since 2006 fullscreen has been broken. When in the cockpit view there is huge tearing so freesync isn't working like it did before 2006.

If I try and use Vsync in fullscreen through the game my FPS will be locked to 60fps even though my refresh rate is at 144hz. Another thing if I run without vsync in fullscreen before getting into the sky my fps is locked to 60fps but after spawning into my plane it goes up to 144fps, I always had Vsync off as Freesync is the better option but since 2006 it's been broken in fullscreen, the tearing is only visible from inside the cockpit, 3rd person view looks ln sync as no tearing is visible.

I now have to play in borderless, my FPS in the selection screen and in the air is always 144fps and is never capped at 60 like in fullscreen now does. I don't select Vsync in borderless but it's either running in windowed Vsync through the OS or Freesync as AMD just started supporting Freesync in borderless but since it doesn't work in fullscreen I think it's Windows OS Vsync that is always at 144fps with no tearing at all.

Some people have also reported that Gsync isn't working in fullscreen since version 2.006 but strangely some say it does, developers will have to narrow down who is and who isn't affected and why.

Below is my bug report for my issue of freesync not working in fullscreen.

My mistake if this is the case. I thought I'd read a post from a 144hz g-sync user that everything was working fine for him. For me going into full screen doesn't effect the in game fps counter (as long as v-sync is off) but resets my monitor to its default of 60hz. (which sounds like whats happening to you as well for some reason) The game menus are always locked at 60fps for me, and therefore g-sync will lower my refresh rate to 60hz while in menus even in borderless.. but once I'm sitting in a plane in borderless my refresh rate goes back up to 100hz along with the fps i've limited to 100fps (looking at the in-game counter).

Since they've already mentioned there are problems with fullscreen perhaps we'll see a fix in the future. Is there an option in your amd software to allow freesync to work in windowed mode as opposed to working in fullscreen only? My display would stay at 100hz even in menus in borderless until I made sure to enable g-sync functionality in windowed mode through nvidia control panel. At which point it synced to the 60fps max the game will run at in the menus, then the refresh rate goes up to 100hz when I'm spawned into a plane.

Any progress on the fullscreen issues? Like Freesync not working in fullscreen and really bad tearing is visible in the cockpit.

Still borked.. I decided to run in fullscreen the other day to s if anything had been done, as ground attack/support missions in PWCG were dropping from like 99 to 25-40 fps which was horriblly stuttery.

G-sync WORKED.. for one session.I almost came and posted about it but as soon as I left the game I couldn't get it to function in full screen again..tried switching from windowed and back and refresh rate stated 60hz while the game was trying to run at 120fps.

I will say that those same ground attack missions were only dropping me to 40-55fps when looking at the action on the ground in fullscreen and back up to 60+ after flying past them with no choppiness. Windowed mode is still the only option to get above 60hz refresh rate for me at least.. so I'm declining ground support roles until I can play in full screen again.

So choices for now are - fullscreen with fps limiter or v-sync on or Windowed borderless with g-sync/freesync if freesync has the option to enable for windowed mode in the ATI software.
