Thank you for the honest feedback! I’ve already fixed the game over screen lock issue and many others. Waiting for the voting period to end so I can upload the new version.
We didn’t optimize graphics at all, I’m sorry to hear it ran poorly on your machine.
There is no fps cap other than vsync, if you have a very high refresh rate monitor(I completely forgot those are a thing, sorry, I usually run mine at a lower refresh rate than what it’s rated for) you can try lowering the refresh rate through your Operating System; or alternatively you can use your GPUSoftware/RivaTunerStatisticsServer to apply a frame cap.
