thats not very helpful. like I said, pre 1.0 versions ran perfectly without any issues but this one does. also my system can handle 16x antialiasing without any problems, especially on a simple 2d game ...
but I've checked and everything is turned on to application controlled ...
Okay after tinkering around for a bit I accidentally discovered that the game runs much smoother on my 2nd screen than on my first one (simply dragged it over to look for other processes that may cause problems)
so after switching some display settings I finally found the culprit:
its the refresh rate of the monitor. My main one has a refresh rate of 144hz and my 2nd only 60hz
After setting the refresh rate to 60hz on my main monitor the game stopped lagging (no it was worse than 60fps... more like 25 to be exact)
I assume that the dev changed some settings to make the game run above 60fps and accidentally swapped the dominator with the numerator in the equation (e.g. game_tickrate_multiplier = 60fps/144hz = 0.417 -> 25fps, instead of 144hz/60fps)
Can anyone tell me where I can reach out to him?
Edit:
I reached out to him and it looks like its a game engine bug (Game Maker Studio)
