Been playing STALKER for some days now. Nice game, but something is seriously wrong with the way the game is coded. It runs like shit when you have dynamic lighting on. My computer manage to squeeze out a ~25 FPS at average but if I turn off dynamic lighting I can max all the settings and get a great framerate. Turning it off makes the game use DX8 instead of DX9 though and lots of atmosphere is lost... So I rather play with medium settings , dynamic lighting and a choppy framerate... >___>
