HI Cyb10101!
Thank you for such a detailed investigation! I'll have to look into this as I do believe vsync should be on by default, which will limit the frame rate to the refresh rate of the monitor (which is preferred over setting a hard cap). Clearly, it seems to not be the case on some computers as even high end monitors would only update at 144Hz.
I'm going to spend some time tonight looking into this and try making a new build as the windows versions on itch are slightly out of date anyway (the Steam version had a few extra updates to address Steam specific issues). I will update this thread when I have uploaded a new set of builds!
UPDATE
I believe I may have found the bug. If you don't mind testing something with the current build:
- Hold the ctrl button while booting the game to bring up the pre-launch menu (it's normally hidden)
- Go to quality settings and set the game to Good.
- Run the game and see if the performance still spikes
It looks like the lowest (Fast and Fastest) settings have VSync turned off, which makes sense as, if you have a low end computer vsync may cause very low frame rates. With Vsync turned off there can be a boost to the frame rate for lower end computers (at the cost of screen tearing).
The proper fix will be to expose the VSync option in the menu which I will try to get into the next update!
