The rest of the game seems to run fine, I haven't noticed a lag on moving the character. But for example the running sound will start only after 100s of ms, same if I get close to an assembler, I will hear its sound only after some time.
Even pressing a button on the welcome screen will incur a delay in the "click" sound.
Is there something that would help debugging this issue? I've tried to look around for previous bug reports but found nothing even remotely close

Cheers.
