Thank you very much for your replies, and sorry for me not getting back faster. I have not yet sent a mail to Spiderweb, thank you for the suggestion. Playing in fullscreen with a lower resolution does not help, at least not at the resolutions I've tried. Another monitor is unfortunately no option. FPS ranges between 24 and 61, but generally revolves around 50-55.

I just loaded up a new game of Avernum: EftP. As soon as the game starts, the graphics are glitchy: every few seconds a random tile will "light up" by displaying a grey or black square. It's a bit as if those ground tiles were flickering. I've tried changing the game area and resolution, that did not help. I never had problems with Avernum on my machine before. I've had to change out the graphics card about two years ago, however, and I guess I haven't played it since then. I own the game on Steam, I'm running Windows 7 Home Premium (Service Pack 1). My graphics setup is as follows: ASUS VS228 flatscreen, NVIDIA GeForce GTX 1050 graphics card (current drivers), Intel Core i5-2400 3.10 GHz CPU. I'd appreciate it a lot if somebody could help me. I'll be happy to offer more info if needed. EDIT: After fiddling around, I found out that "Play game in window" from the start-up options screen seems to remove the flickering. How do I go about achieving that in fullscreen mode?
