If you have any problems with any of our games please open a ticket with our support.
Concerning the Gorky17 case... Please try to run the game without hardware acceleration on a software renderer. Developers didn't left it there for nothing. (it'll help you in most cases)
As you can see above I have opened a ticket with no response thus far.
Also, the Software Render is terrible and makes the game looks like trash. I really think GOG needs to fix this issue and simply tell people to run it in an inferior manner.
If this is the case, and this is the tact you are going to take GOG should be up front before people buy the game and tell them that it only works with Software Rendering.
At this point it is a waste of $6.00 and it has been uninstalled from my hard drive.
