OpenGL problem
 

I recently installed Il-2 46 on a new Windows 7 64bit laptop, using a Radeon HD 6770 graphics card with 2GB graphics memory, which comes with OpenGL 4.1. But for whatever reason Il-2 46 barely runs at all when on OpenGL. It works quite well on DirectX, but when I change it to OpenGL it gets about 2 frames per second. The main reason this is an issue is because I want to use the Perfect landscape setting available only to OpenGL. Does anyone know what the problem could be?

catalyst version? do you already have an atioglxx.dll in il2 folder?

The only Catalyst version number I can find on my computer is 2011.0315.958.16016, although I think that this isn't the number you're looking for. And no, I don't have atioglxx.dll. What is it/where can I get it?
Thanks for the help so far

yeah, this number tell me nothing sorry :-), try installing latest drivers

ok, so I finally managed to get the correct update despite a bad internet connection. OpenGL is now functioning well, but despite changes to conf.ini I still cannot apply the Perfect setting for Landscape detail. Is there some condition or setting that might be preventing me from using the Perfect setting? Also the game refuses to conform to my computer's screen resolution, but I suppose that might be because Il-2 doesn't do wide-screen?

Something in my memory...but I can't put finger on it. Yes, has to be Open G/L. But I think there is something else. Maybe also has to be ansiotropic? And maybe the water setting? I think maybe some of the water settings only apply to direct x or open gl. Also make sure all the other settings are on high/excellent...etc. Can't really remember, but try messing with those to see what happens.

Are you patched up to 4.101. You can force your resolution under [window] in your config.ini. Sure there is a thread on this somewhere.

I'm not yet patched, but I know that I've been able to force the resolution on other computers I've installed it on with previous versions. Currently I'm running v4.08m. This is the first Windows 7 machine that I've tried Perfect on, and this machine has a very capable graphics card with OpenGL 3.1 or so, so I'm just confused as to why it doesn't work. I seem to recall on the older XP machine that I used I would put at 1280x1024 and then select OpenGL, and Perfect was available, and then I would change the config.ini to Water=3 and Landgeom=3 and so forth, but for whatever reason it just isn't working on this machine. When I put 1920x1080 in the ini file, the game starts up at 640x800.

And you have attempt stencil buffer selected? if not set it on in game, or in Il2Setup.exe

Yes, I have Attempt Stencill Buffer on

have you tried hardwareshaders=1, this needs to be set in conf.ini for perfect mode
