Windows 10. 24GB ram. AMD CPU. nvidia GPU. Display is 1920 x 1080. Latest nvidia drivers (today).
Most of the games ran fine, but a few failed to run. Might be my system, or maybe it's something to do with a particular Godot build.
(The games that didn't work are: GWJ6: Out of Place Cacti, New York Cactus, and Cactus Yeehaw. Not sure if there's any commonality there.)
There's no error message that I could find. Do you know if godot produces a crashlog somewhere?
Not sure if it'd help, but we could maybe try exporting it from the latest Godot 3.1 beta 5 build from their website?
