Tried it on my old laptop (2-core). Is the input lag normal or is it just my slow laptop? Still had like 30-60 fps in the tutorial area and around 20 in the next one.
Also there is some inconsistency to my mouse turning when it sometimes suddenly spins way faster.
Btw Im stuck, after I got the second symbol for the next door I cant find the key for them. Where is it? edit: Nvm, found it, it was behind the rubble.
