OpenGL still about 20% slower

[Gargi]

Hi! I have a 7800GT and WinXP and Vista64bit in a dualboot. Currently I'm using the 158.24 driverset. Since I have Vista installed I've lost about 20 fps on Doom3. Under XP I get about 105 fps and under Vista 83. That's about 20 % loss in performance. Is there anything wrong with my setup?

Nope, just Vista. Enjoy ;)

Hehehe...

Okay, but under Direct 3D it seems to run quiet as fast as it does under XP. So I wonder why they won't manage to raise up the opengl performance nearly at the same level.

Just need to finetune the driver for OpenGL :)

I haven't noticed any diference when playing Prey for example. Or DX/UT99 using modified high detail OGL renderer.

I mean also Call of Duty 2 is slower cause I notice framedroppings being definitly not under XP. Maybe there is really need for tuning the driver, but I don't know where to start.

CoD2 is not OpenGL

Shame on me, you're right. Guess it is since CoD1 was based on openGL.
