That is unfortunate, we haven't heard of similar performance issues before. If it isn't too inconvenient would be able to try a different browser (also make sure graphics/hardware acceleration is on on that one too) to help us diagnose the issue.
We'd love to do what we can to sort it out so you can give it a proper go!

i tried on Safari, Brave, and Firefox. FF had less lag but still there, seemingly happens when i go to enter a different "area" - past the fence, into the room with the lever, through the mouth door. Hardware Acceleration on for all. i can try on Opera tomorrow and let you know - also if you ever happen to release a downloadable build, that would be great!
