I've seen people test it successfully on linux, what hardware did you test it on ? i know my 4-5yo gtx1050 / i7-8750h laptop doesn't run it very smoothly, but i don't think i've had input drops
OS: Arch Linux x86_64
CPU: Intel i5-1035G1 (8) @ 3.600GHz
GPU: Intel Iris Plus Graphics G1
I'll try again tomorrow and try to give you some more details. I tried it out with a GameCube-type controller.
