Sudden frame-rate drop on windows

    I'm experiencing some strange behavior for my project w unity (v 2018.2.vf1).

    I'm testing my game in the editor and getting smooth 60+ fps. I build the game for windows and still get smooth 60+. Next time I start up the built version of the game frame-rate is now aporx at 30 fps. Same with the editor.

    Nothing has changed. All I did was close the build and restart it. Restarting my PC and Unity does nothing.

    Profiling the game I find that it has a normal profile (from previous) - however the whole curve seems to be shifted towards slower performance.

    NOW I'm working on an older PC and I'm yet to try to reproduce the issue on another PC but I'm kinda getting the feel that windows is somehow throttling the frame-rate due to some system-issue.

    Could I be on to something? Is this a known issue?

    Thanks a bunch for any insight you can offer!

    That's weird! I've not heard of problems like this before. Usually if something suddenly goes slow, it is a particular idea of code, rather than it gets uniformly slower. Is your hardware overheating by any chance?
