I don't know if you are aware that Vista is really bad at OpenGL due to m$ design decisions that may be interpreted as almost a stab in the back of OpenGL? DirectX is really no fun in IL2 as you get no perfect settings etc. but it would be interesting to know the fps you get using DirectX?

As I use a dual boot config I have tried OpenGL in Vista 64 premium and the fps is a lot worse than Dx (which looks a lot worse at the other hand)...

I found some old benchmarks i posted at Ubizoo way back when (feb 2007, same rig but IL2 version 4.0.7.1m - I used Vista 32 Ultimate back then instead of 64 which makes no difference I guess).

Interesting to note is that I lost 20 fps in BlackDeath (at the end of the quote) between Vista and XP. Not far from your score in Vista. Sure the dirvers have improved a lot since then to I'm gonna reboot and try it out. At the other hand the 4.09 landgeom=3 makes the 72km range happen that should do some negative stuff for the fos (5 fps as noted in this thread).

I first booted it in Vista using 100.59 forceware and IL2-1946 version 4.0.7.1m

I used 1280x960x32 and maximum settings (not perfect to be able to compare OGL and DX at first).

I just took a quick mission (A20C-Crimea-No AAA) and flew straight forward default FOV inside and checked the FPS using fraps. Default forceware settings, no anisiotropic filtering or aa, but with vertical sync off (no fun fps otherwise).

DirectX - 105fps
OpenGL - 70fps

Then I did it "my way" using 1280x1024x32, OpenGL perfect settings, water=4, 16x anisotropic and 16qx aa, and then I got 80fps. Weird, better than the test above with no bells and whistles.

OK, so how about XP then?

Same settings as above (accept forceware 97.92 for XP).

Standard settings:

DirectX: 150fps
OpenGL: 150fps

And "my way" all bells and wistles: 115-120fps (and it looks awsome! )

...

To be a bit more professional about the testing, I did the BlackDeath track fraps test as NerdConnected did... "my way" settings (OGL 1280x1024x32, perfect landscape, water=4, 16x anisotropic, 16qx anti aliasing):
