flv2358: I've installed the game and after the initial setup the game seemed to be running perfectly fine. That is, until I've reached the water part of the training. At this point the framerate dropped significantly, making the game almost unplayable. I have a Radeon HD6300 / Intel Hd 3000 (switchable) graphics card. However, the game chose the latter during the configuration and I was unable to change it in any way. Did anyone encounter a similar issue?

On a side note: I've played a non-gog version of Deus Ex before I switched from Win7 to Win10 and it seemed to be running perfectly fine. Also, I've tried Kentie's launcher but it doesn't seemed to work on Win10 - after trying to execute it nothing happens.

flv2358: I've tried shutting down the card but it resulted in the game choosing software rendering only :| Thanks for the reply though!

flv2358: I've found a partial solution, or at least it has helped to deal with those performance issues and minor graphic glitches with my card. Simply switch the color depth from 16 to 32-bit and restart the game. In my case, it runs much smoother.
