It's not really playable at the moment. For some reason It's uses 100% of my GPU when I try to run it (and I have a RTX4080). Maybe a FPS cap or something?
Edit:I found out it's using my built-in GPU instead of my dedicated GPU to render the web page for some reason. Don't know how to fix that.
Thanks for investigating and sharing what you found! v0.33 adds 30/60 FPS limits, lighter default graphics, and reduced rendering while paused. It should also be easier on integrated GPUs, though the game can’t force your browser to use the RTX card. Please try Low + 30 FPS in Settings (O) and let me know how it runs.
