Windows 7 Beta- Runs slow, was perfect on Vista

[jawslover]

Before I upgraded to Windows 7 Beta, Defcon ran perfect, high FPS, everything. Now, after I upgraded, the framerate doesn't go above 8-10 fps in menus, and 2-4 fps in game. My specs are:
Core 2 Duo
8800 GT Nvidia

And the surprise is...?

My understanding is that many of the drivers for Windows 7 still don't really support OpenGL that well. As Defcon is an OpenGL game, it is no surprise that it runs slowly. I would wait to complain about issues that Defcon has on a Windows 7 install until after Windows 7 is out of beta.

i know some forum members don't like it when old threads are revived, but:

i am pleased to announce that defcon runs perfectly fine on my windows 7, build 7600 x64

(PS - what a great OS!)

Clarification, we don't like it when old threads are necro-bumped for no good reason. Your post is informative and might have (current) value.

I just installed the game on Windows 7 Ultimate 64-bit, Build 7600. I never played it on Vista.

Getting less than 0.5FPS including the mouse running at the default resolution of 2560x1600. I dropped it to 1280x800 and it was closer to 1FPS.

Install a proper graphics driver from your GPU vendor; that was the usual advice given to those experiencing the same problem on Vista.

i still have build 7100 and it works fine on my end, update the latest directx9 as well as your gpu drivers and you should be well.
