50% Lower Frame Rate With New Video Card

[Aviar]

I just upgraded my video card from a NVIDIA GTX 260 to a NVIDIA GTX 650 Ti. The problem is that my IL-2 frame rates are now HALF of what they were on the 260. All my settings are the same and the driver version is also the same (the latest driver version: 314.22).

The 650 is PCI 3.0 ready but I believe my motherboard is 2.0. However, the info with the new card says that the 650 is fully compatible with legacy 2.0 components.

Any idea why I am getting 50% LOWER frame rate with the new card?

Did you just drop the card in and go from there?

In my experience, although it's a bit dated now, it's always a good idea to completely remove the video card drivers before installing the new card. Then when the new card drops in, it can go in cleanly.

Uninstall everything from nVidia from the Programs list. Download the latest drivers again. Install.

Should kick things back into gear. If not... then there may be some setting with IL-2 specifically that might be causing an issue.

This is likely to be a result of the power saving features of the GTX 6xx series. Go into your Nvidia control panel and make sure you 'power management' set to 'prefer maximum performance'.

Good Luck Aviar!

No, I installed the card correctly...remove old drivers and then reinstall new drivers after the new card goes in. Also, I did it twice, after I saw the poor frame rate the first time.

The reason I originally said the drivers are the same is because I upgraded to the same drivers just a week before and they were were working perfectly with the 260...so I know it's not the drivers.

I don't see 'Power Management' settings in any of these....

**EDIT: I just came from another forum and someone posted screenshots of their NVIDIA Control Panel 3D settings. They have a 'power management mode' option in their 3D settings. However, in MY 3D settings I DO NOT have such an option. I do have the latest drivers, so I don't know what to say.

Problem solved! It seems to have been one simple option in my 3D settings.

In the 'Antialiasing - Mode' setting, I had the 'Override any application setting' chosen. This gave me a 50% DECREASE in frame rate compared to my old card.

After selecting the 'Enhance the application setting' option, I now get at least a 30% INCREASE compared to my old card.

Thanks to all who responded!

This is natural, but in case of Il-2 you will get no antialiasing at all with these settings (you need 'Override any application setting' for this).

I also have the GTX 650 (without Ti) and I can run the game very fine on highest settings with 4x MSAA. I suspect some more fancy AA settings in your driver options. Would be interesting to see it. You can loose a lot of framrates with wrong settings, and on the other side you can get more performance and eyecandy, if you do it right.

It will be nice to see a video setup guide for IL2! I think a lot of people with good computers can't get the best out of them for this game and a lot of times nailing the best settings for the game is a pain in the a(s)s.

There were lots of guides for the older cards like the Voodoo4 4500 and old Radeons where every tweak was needed for the original game.

But as things progressed and settings were able to be turned on (perfect mode) there became a "standard" setting for a long while for ATI & Nvidea become settled in and most tweaks were made out side of the games conf.ini settings.

The newer generation of cards need a new guide made as up to a GTX 560ti Phantom 2gig the setting are the same as older series. even in the drivers :)

Is the AA you were overriding to possibly super-high and maybe by cutting back just a bit you can have some AA without any slowdown?

Also, what's it going to be like when up upgrade the mobo and get PCI 3.0!

Maybe there's some kind of wait state setting that will help till then?

I'm sorry to disagree with you, but I certainly do get AA when I select the 'Enhance the application setting' option.

Look at my first two screenshots. I have disabled all of my AA settings in my NVIDIA Control Panel and you will see how the game looks with no AA.

The easiest place to note the 'jaggies' is the cockpit frame directly under the Emergency Exit sign. Also note the current frame rate (292).

Now look at the 3rd and 4th screenshots. I have enabled the AA settings and selected the 'Enhance the application setting' option (the option you said "...will get no antialiasing at all...").

The 'jaggies' from the 1st screenshot are now gone. This is proof that AA is working with the 'Enhance the application setting' option enabled.

Also, you can see that the frame rate has gone down to 265...further indication that AA has been applied.

Oh, yes, but thats just because you are using FXAA - which is a simple post calculation of every picture. It works whatever you choose.

However, it also blurres the dots (contacts), which makes them quite hard to notice. The game is old and not very suited for new technology. I suggest 8x Multisampling AA (or 16x if you like). It smoothes the edges very well but leaves the rest of the scene clear and sharp (i.e. the landscape). And it will give you better framerates as FXAA.
For Multisampling AA you will need 'Override any applications setting'.

For anisotropic filtering I suggest 'Application' as IL-2 comes with a build in mode, which works just fine (saved FPS!).

And you can disable the 'Transparency-Antialising'. It doesn't do anything valuable for this game and just sucks down your framerate. The same for 'Antialiasing-Gamma-Correction'.

Here is my setting (just in german):

BTW... you should change your signature then. ;)

I have the same card (EVGA GTX 650 Ti 1024) and had no problem running the 306 driver (am trying the 307.74 now) using the "override any app. setting" in the Antialiasing-Mode. I run 8x AA and Anisotropic and get no jaggies whatsoever. Only thing I havent upgraded is the Precision X program as the newest leave out some monitor display options that I like.

I also have the "power management mode" in the 3D settings but I have an AMD dual core CPU.
