Game Window Slow

Recently installed Unity om a new pc. Its a beast of a computer so power isnt a problem. But when ever I go into my Game Window (Play the game in the editor) the fps drops to 12 and considering when i compile the game and stuff I get 300+ I am confused. When I do run the game in the editor the console is spammed by stuff like this:
Allocation of 752 bytes at 056b50f0

Any help would be welcomed. Have a nice day

If something is spamming the editor console, it can slow the game down quite easily. Which version of Unity are you using? Have you tried whether updating fixes the issue?

Anyway, you should send them a bug report.

This is probably related to your particle systems, which version of Unity are you on?

You can follow the issue here (we have a fix coming.)
