I am posting two pictures. The first shows what things should like like all the time. The second is what my screen frequently changes to for no apparent reason and then back again to normal.






I am using two 7800GTs in SLI XP Pro 32bit.

Seems the transparency of the backgrounds in the gas / sparkles is going translucent to black.

The problem is exclusive to OpenGL mode. All resolutions 16bit and 32bit, etc.

Interestingly some maps are worse than others.

Can anyone identify this issue?

Thanks in advance.

By any chance did you tweak your fps settings, when i used some hl fps tweaker(changes settings to increse fps) this exact same thing happed to me. You could also try turning anti aliasing off and some other stuff :\ in the video settings.

I already saw this problem on steam forums...


Try updating drivers or using olders drivers, and it should work fine.

Ill give it s try. Thanks for the replies.
