Launching from Steam, this game just works. The launch command is merely to monitor hardware and use dGPU, but it will run without any custom command anyway, just a tad slower. On my machine, even on iGPU it defaults to Epic graphics settings for all (60fps average is reachable, dGPU raises by about 10fps only to 70s). So this is a very lightweight game. Neither slowdowns nor stuttering over time, very well optimized.
