I’ve first experienced this with game LIMBO and couldn’t figure it out until today when it happened in Tower Wars game again. And the symptoms were too peculiar to be a coincidence.
When you exit the game, screen remains black. No mouse or keyboard input seems to do anything as no amount of Ctrl+Esc, Alt+Tab, Alt+F4 did anything. If you had music player playing in the background via music player, music will continue playing (meaning system didn’t actually freeze).
Affected devices and games:
- NVIDIA GeForce graphic card (GTX 980 in my case)
- LIMBO (tested game)
- Tower Wars (tested game)
Change the “Preferred refresh rate” from “Highest available” to “Application-controlled” in NVIDIA Control Panel.
The reason I’ve always changed this to “Highest available” was because I have a 144Hz monitor and I want everything to run at such high refresh. Apparently, with games that enforce own refresh rate (which isn’t 144Hz, but 60Hz instead), this somehow conflicts and causes this lockup with black screen.
