When I run IL2 on any map using OpenGL my framerate will drop, or stutter, every 1 to 2 seconds. I have checked all over this forum to try to find a solution to fix this. I even saved my old copy of the game and just did a clean install but my problem remains. The problem goes away when I use DirectX, but I would prefer to have "perfect" settings for the ground textures. I am 99% sure it's not an overheating problem.

I have:
Windows XP
Intel Core Duo 2.0 Ghz
ATI Radeon X1600
2 Gb RAM


Here are my conf.ini settings:


[Render_OpenGL]
TexQual=3
TexMipFilter=2
TexCompress=0
TexFlags.UseDither=1
TexFlags.UseAlpha=0
TexFlags.UseIndex=0

Anyone got any ideas?

I've heard that vertical sync can cause stuters with some ati cards, it might be worth trying setting it to 'always off' and see if that solves the problem.

i saw that on another thread but it didnt work. Ive been combing though the help sections here but cant seem to find anything that works. any more ideas?

Hmm. I have same HW, with no issues (its in an iMac though)..... There was some texture that caused problems in one of the mods, but I forget what it was. When putting in a smaller texture for the offending one, it all went away. These are my current settings, though it still works fine with the settings pretty much maxxed.

can you remember which texture it was that you replaced?
