Only technical thing that matters... SLI.. yes? no? PLEASE!

[Thrasher]

Graphics card upgrades wouldn't even be on my mind.. if you would simply implement SLI. There is absolutely NOTHING this sim could throw at TWO NVidia gtx 670's in SLI that they could not handle.

 

Being it IS a flight sim.. you would think SLI would be rather important to the devs .. as the only reason I and many others USE sli/crossfire.. is because we flight sim......

 

Just saying.... The game has been released for months now. Screw Occulus rift support when you can't even get SLI an old.. long time.. industry standard...

 to work.....

 

Hell I use it in ROF all the time..

 

What gives? Will IL 2 be 3 years old before we finally see it?

ER,....SLI support implemented with profile 2 NVidia driver updates ago, is turned on by default in game, the greyed out checkbox is redundant or maybe left until crossfire added by driver support

I stand corrected!

[Thrasher]

I ran tests...

 

Regardless of what may have been said, SLI is not working. I ran a test with only one video card enabled and then in SLI, no other changes made.. there is absolutely no fps increase when using SLI which indicates that it is NOT working properly.

 

With settings at Ultra at a resolution of 1920 x 1200 the fps hovers around 33 to 41 in either single card or sli modes in the NVidia drivers. SLI enabled should run this game at a smooth, rock solid, 60 fps ... the limit of my monitors refresh rate of 60 hz.

 

Like I said there is no improvement whatsoever....

 

And no, there is no problem with my system, it uses SLI to wonderful effect in every single other game I play.

And no the GTX 670's are not too old, a pair of them in SLI can out perform a brand new GTX 980.

After goofing around with the settings for about an hour... I manage to eek out close to 60... 53ish to 58ish sometimes 60... by going into the NVidia drivers for the game and changing sli options from 'NVidia recommended' to 'force alternate frame rendering 2'.

 

I still think this needs some tweaking by the devs.. not complaining about the game ... I LOOOOVE the game... and Rise of Flight as well.

 

 

EDIT: Nope, alternate frame rendering 2 is no good. While I did notice an improvement in FPS, it cause graphical anomalies on the ground that looked like large flashing areas of dark gray...

 

If SLI is implemented in the game, it needs a lot of work.

Try these threads may be some help there, or ask/PM those with SLI working satisfactorily

I see utilization on both gpu.

[Dakpilot]

Also what are the rest of your computer specs, BoS is mainly CPU bottlenecked for FPS and GPU dependant for graphic enhancement/effects

S!

 

Can Confirm this. Running on 3 GTX 780 which are all in usage during game play, but only at 40-60%. About 50 FPS on the ground, they get better at higher altitudes (100 FPS and above). Games like ArmA 3 are also limited by the CPU, so it seems to be a common problem with simulators. War Thunder on the other hand has 100% usage on all 3 GPUs and seems not to be bottlenecked by the CPU (120-200FPS and above).

 

PS: I was running this game on two GTX 670 before too (still have them in my backup PC) and already experienced a GPU bottleneck with them. Usage was at about 80% on both cards, again ~50 FPS on the ground with the same CPU.

You have a good CPU there. Are you running at 4K?

I had to delete the individual profile from my NVIDIA control panel and then recreate it to get SLI going. (ran without a profile altogether too!)  Not sure why, but it did.

That is what is happening to me. My processor is more than strong enough to handle the game, it is an intel i7 3770 paired with 16 gb ddr 3. On the ground my frames are anywhere from 39 to 55 but in the air it usually smooth's out to a good 60. I will be buying a gtx970 soon and will see if that single card will make a difference in fps... will use one of my 670's for physics and eventually replace it with another 970 for 970 sli.

About your CPU being the strong enough, just because it is an i7 does not mean it is strong enough. Just test if both GPUs are used in game with a program like MSI Afterburner. You can get 3 different results. Both GPUs are running on 100%, means your CPU is strong enough. If only one GPU is used, indicates that SLI is not working correctly, updated your drivers in this case, cause it is supported by BoS. Both GPUs running on the same percentage but not on 100%, means the CPU is the bottleneck, which is most likely the case in this game.

 

Also keep in mind that only a few games support PhysX (on GPU), BoS does not. If you don't play any PhysX games at all, it would make no sense to keep the card.

Im running on a 3440x1440 (21:9) screen with DSR on 1.2, which means 3768x1577.

Nice! I saw a 30" one of those from LG I think it was. Sounds excellent.
