https://imgur.com/P6wZ5v5 try this to allow the game to use more ram. this is usually only a problem on windows 10 but still worth a try. for kamilia games you could maybe try to remove all japanese signs from folders/txt files. this can cause issues if you don't use japanese local
No change, even while on Japanese applocale. This is especially strange because my 10 year old laptop can run fangames fine without downloading any tools or prerequisites, but this desktop can't.
EDIT:
The issue appears to be some sort of hardware incompatibility, since far weaker computers can play but this one cannot, even when both machines are on a fresh install of the operating system.
My hardware is as follows:
CPU: Intel i7 3770k OC @ 4.5GHz
GPU: AMD R9 390 8GB
RAM: 16GB DDR3 Kingston HyperX @ 1833MHz
Mobo: Gigabyte GA-Z77-D3H
It might just be a peripheral but I haven't a clue which one. I might have to test those as well.
EDIT 2: It appears Gamemaker is just being Gamemaker. However, by running a Virtual Machine with hardware acceleration enabled I can play fangames which don't work on my host machine, so at least I have that as a bandaid fix since nothing seems to work for native support on the host.
