Currently running:

 

i7-4770k

Z87 Sabertooth mobo

16Gb RAM

EVGA FTW 1080

 

All latest drivers.

 

I have the graphics settings maxxed save for no HDR and screen resolution at 640x480.

 

SS is at 1.1

 

On my test mission (Kuban, 8 x Spits (mirror on) v 8xJu52 on average, heavy cloud, MSI Afterburner reports CPU useage at 60 with the core reports between 58 and 80.  GPU spikes at 98/99.  This is with a frame rate around 45 that drops to 30 or so.  ASW is OFF.

 

Would moving to an i7-8700k and faster RAM etc help with the framerates or is it solely a better GPU that is needed?

Edit: i7 is running at 4.3 and I’m looking at upgrading to an i7 8700k so ram etc will also be quicker.

Yeah - not sure what you're RAM is currently running at, but while I like my 1080 TI I think you'll get more bang from CPU/RAM upgrades/OC than you will from moving up from a 1080 to a 1080 TI at the moment.

 

What sort of results are you getting on the benchmark track tests with your current rig?

No need for upgrades, just tweaking.  There is something wrong with those numbers. 

 

Here are my specs (much lower than yours)

i7 4770

120gb ssd with OS

500gb SSD with game

12gb Ram

gtx 1050ti overclocked using software

Nvidia driver 388.00 (not the most current but is the most stable for me)

 

Game settings:

res: 1920x1080
no HDR or SSAO
shadows high
mirror complex
landcsape x4
landscape filter off
grass normal
target fps off
Antialiasing 4

Nvidia settings:
Antialiasing application controlled
MFAA off
anistropic filtering application controlled
lod Bias allow
quality high performance
trilinear optimization off
threaded optimization auto
tripple buffering on
v'sync on

I have tried the Kuban map with 8 spits with mirrors and  8 ju52s and was getting steady 60fps without any drop whatsoever.

Interesting. Weirdly I was getting 60-90 until around 3 or 4 months ago then following a game or driver update (never figured out which may have caused it) I had an instant 20-30fps drop.

 

Wedgewood are those FPS on the desktop or in Oculus Rift. I get 60fps at 3440x1440 on the desktop.

I just realized I mis-read your post and didn't see the VR part.  I'm getting those numbers in desktop mode.

sure a new processor will help you knock it out of the park. but both you and wedge wood have a few waaaay over the top settings. 

 

your system should run run 70fps+ min with the correct "maxed out" settings.  your settings aren't "maxed out" (most fps highest settings) , they are "over maxed." (highest settings , low fps) 

 

try:

 

low or med shadows

try balanced or high settings (clouds fps!) - surely you're not on ultra

no mirrors 

2x distant max

try sharpen off

2x aa max

 

1.7 ss

 

 

to run that scenario like you want to with all the most intensive settings with clouds on Kuban, I'd guess you need a i-8700k @5.0Ghz, 32gbRAm 4000+, and a 1080Ti for 80fps +

 

 

also wedge,

 

I think those nvidia settings are meaningless in VR. just high performance important i believe

Check your Steam VR settings.

I have seen reports by some where an update had reset their SS setting to something very high...

 

Edit - never mind read your post again, see you have it at 1.1...

1.1 is via OTT but I’ll check the Steam VR settings.

 

katdog, for me the point is maintaining graphical fidelity with a high frame rate. I could drop the settings but I just don’t want to. I’m silly like that!

Tom - you can also try turning off the SS in OTT and just using the one in Steam VR instead. May or may not have any effect, but I've seen it recommended in some scenarios.

Super.

 

Thank you very much indeed.

Its a decent link and provides concrete evidence that the CPU is extremely important for VR in the case of IL 2. I think I've taken my I5 4690k as far as it will go and sometimes you need a little push to take the next step.

 

I'm extremely tempted by a CPU upgrade so have started researching the  i7 8700K . The i5 8600K might be a decent compromise for me as it seems to compete / better an i7 7800K without breaking the bank.

New kit = 25+ FPS improvement.

 

Completely unscientific testing but with all settings as they were previously I now get 75+FPS with Ultra settings with everything at max but with HDR off, AAx4, SS at 1.1 (OTT).

 

Mission is 8xSpits v 8xHe111s (novice) over Kuban with heavy cloud. Complex mirror on and HUD on just to stress things.

 

Maybe there is a benefit to a fresh install of W10, drivers and the game but I’m happy.

Congrats, some nice numbers there!

 

I will likely be doing a new build at some point in 2018.

Brilliant news.

 

I appreciate the better FPS but do you feel it worth the upgrade in relation to increased visual quality. Do things look noticeably better at Ultra and your new settings ?

I had those settings before but in an indeciferable way it looks better. More FPS helps and the rest may be placebo effect but nicer overall.

 

I can understand those that want a rock solid 90fps for multiplayer purposes but I no longer have the competitive side I used to have and I like the eye candy more.

 

I’m looking forward to seeing what the 2080 does when it is released.

Note that the 8700K or 8600K will require a new MoBo+RAM+Operating system.

 

Another alternative is to sell your current CPU and buy just a new 4790K. Yes, it is a veteran CPU, but a "pata negra" CPU.

There is no telling how much PC enthusiast hardware has been sold since VR started to come more into the mainsteam.

That never ending quest to try and get 90 fps consistently, in something as complex as a flight or racing simulation.

It just ain't going to happen, not on today's hardware no matter how good it is, but it is getting closer to reality..

 

Having said that, I would certainly not recommend sinking any more money into your current build. An 8700k or 8600k with the new platform would certainly be nice. Just be aware you won't quite reach utopia yet, but will be a step closer. Maybe when next gen vid cards come out.

 

If I were to upgrade my system right now, I would go 8700k no question.

I am becoming due though, and will certainly be looking at doing so at some point in 2018, hoping the latter part. I will then see what is out there for me then.

 

I myself am content with my VR performance for now, which helps me hold out a little longer also. Certainly not setting the woods on fire fps wise, but very smooth and enjoyable for me, and that is all that matters. 

I can turn the fps counter off.

;)

Congrats for your new performance.

Having a 1080 GPU, why do you only use 1.1 SS in OTT. You card could easily support 1.5 and you will gain visual details:

 

https://forum.il2sturmovik.com/topic/31307-how-ss-decreases-your-fps-testing-results/

 

1.3 drops the FPS by an in-game noticeable amount and the GPU stays at 99 (MSI Afterburner) for extended periods.

 

I also don’t think any graphical improvement (minimal to my eyes) is worth it.

 

FPS isn’t everything but I am sensitive to FPS drops. No nausea but a feeling it is jerky even at 45 FPS.

Love the idea of turning the FPS counter off  :biggrin:

 

This game has destroyed me since 2003 and I've been forever chasing Utopia.....I then fell out of love with it and suddenly VR was here but I'd just jumped on trackir ...and I was smitten all over again.....gone so long that I'd lost my old log in .....lets be honest we all need a decent reason to upgrade so here it is.  

 

Interestingly I ran a few missions on Ultra....No real problems, it was only combat it all got slightly edgy...but doeable so yes I don't really have to upgrade but why not...probably early next year when prices come down on the 8700.
