I too have a 550TI, and am experiencing CTD w/ high AI count. Sorry to be so unlearned here, but how do you get this game to run in OGL? I have searched the menu, folders, and Nvidia control panel. Do not seem to be able to find this. Also my "conf" file does not have the same varibles in the same order as your suggestions.

Thank you for your help, as I really see the potential in this piece of software. I just spent $150+ on this card, before learning that it was really nowhere close to the 560. So cannot buy another for awhile. Would like to take advantage of the fine advice on here. - wuffman -

On your Setup screen. (See screenshot)

Aviar,
Thank you for the reply. That is indeed the screen I am looking for, but have yet to find it??? Can you please give me the big block instruction as to finding it?
I am running XP, so that may be the issue.
Intel Core 2 Duo 6850
Asus p51 mb
Evga geforce GTX 550TI
4GB1600 DDR3
Again, I appreciate your time.

It's an application file in your IL-2 folder named 'il2setup'. Just double-click on it.

I just replaced my old integrated nVidia nForce 430 w/128MB with an nVidia 8400GS w/512MB that I thought didn't work but it does ;) I turned my in game IL2 settings up to max and it's smooth as butter, anyone else out there with an 8400GS wish to share their thoughts/settings for IL2???

Rig Specs are:
AMD 2.5 Ghz Dual Core
3 GB DDR2
8400GS 512MB

Also, is anybody using a GT430 1GB DDR3 and wants to share their opinion and settings for IL2?

Hi everyone I have a GeForce GTX550Ti,

I cannot get AA to work in OpenGL, it works fine in DX. Just about beating my head against the wall on this one.

I'm pretty sure it is a OGL issue. I think the newer versions do not support the old IL2 very well. I'm about ready to try every GeForce GTX550Ti driver and was hoping what version of drivers are you using, I know this topic is a month old and I am using a newer versions (I'm using 296.10 now).

I'm comfortable with Nvida control panel
As well as with nvidiaInspector (Does this override Nvidia control panel, or fine tune it?)
I've edited more than my fair share of the config.ini file (I've been playing Il2 since its conception, have played this game since before my ATI 9800GT, can't remember what card I had before this, heck my first graphic card was a Mach32, but I digress, so I've been tweaking the Config.ini for sometime)

So if you've had this problem but now you have it fixed. Please post here and share your success.

Thanks for you help.

Update Still no fix after attempting all Geforce Drivers form Nvidia. Now I have no AA in DirectX or OpenGL. I've tried using NvidiaInspector to set the AA to override, enhance but still no effect. It as if the new OpenGL 4 doesn't support this game anymore Any advice or assistance would be greatly apreciated.
