Hello everyone! I've installed deus ex goty on my laptop (win8.1), i've chosen direct 3d support as a renderer (it was recommended) and when I start the game, the framerate is a little bit low. I started the tutorial and during that the framerate was't that bad. But when I reached the part where I have to swim, the framerate becomes so low it makes the game unplayable. (propably it would happen again when I get near water.)
I've tried turning the affinity from multi cores to a single core, i've downloaded the kentie.net pack and placed it on the right folder but they didn't help. I've also tried to change the renderer but only direct 3d support worked.

Could anyone help me?

Ok I've solved it. I've reinstalled the game and did nothing but changed the colour depht. Now It is working without problems.

thankyou i have this problem too
