Windows 7 x64 vs Vista x64 - Left 4 Dead slower?

[drlunanerd]

I'm playing Left 4 Dead on Windows 7 x64. Frame rates are down compared to Vista x64 SP1. Not what I was expecting. Playing both on same low quality settings.

I'm running on a Radeon x1600 (MacBook Pro). As far I remember the graphics drivers are the same version under 7 and Vista (i.e. the Boot Camp driver).

Does anyone know how to speed things up? Are there newer drivers available for the Radeon X1600 (possibly hacked ones)?

Have you tried to stop the Themes service. I have problems running COD4 which seem to go away if this service isn't running. I'm running that on a i7 PC though and not on my MBP but it could be a common issue with Windows 7 during the beta phase.

Thanks for the tip
However I think I will revert back to Vista, but slim it down (it takes too much disk space as it is).

No worries

That is definitely a driver issue. Win7 64 and Vista64 fps performance are pretty much the same, so it sounds like there's a driver problem going on here (no surprise, it is a beta OS after all). Have you tried installing the latest driver from the ATI site (just use the Vista64 driver)?

Thanks. Yeah I tried that but got this:
