Gamma oscilation (white screen)

[JulietAlphaNovember 10]

Well, I've got some strange fluctuations of gamma settings during the game, where the picture goes from normal brightness and starts to rise till the picture is fully white and back to normal. This keeps going all the time like an oscilation. First I've thought if the character looks to the sun it will blind it, but this is happening also when the character is still and not in the sunlight or in a room. I've patched the game to 1.02 version and it was still happening the same as in ver 1.01. Any ideas how to fix this? I'm using non-steam version and my GPU is HD6870, with latest drivers.

What is your video memory setting in the video options? And I presume it's also a legit copy? (so we can exclude Fade as the cause)

This happens a lot with ATI cards (I have an HD5970 OC). It happens especially if you have the HDR settings on high and Vsync off. Try one of two things;

1. Turn HDR down and leave vsync off.

2. Turn on Vsync.

See if this helps - it usually does for me.

Thank you Jedra, your settings fixed the problem. The problem hasn't occured since then, also I haven't noticed any change on graphic quality.

Glad that worked for you. I don't know why it happens with ATI cards especially. I have seen it occasionally in other games (Crysis 2 being a prime example), but mostly in Arma 2, but not yet in TKOH.
