micro stutter after first ability usage

[Burger_Kyle]

after the new update, each time a hero uses an ability for the first time, whether my own or another players, i'll get a micro stutter. never happened before this patch.

This has been a thing for me since I switched to vulkan by the end of the year after this shader prewarm issue cropped up in november. It is consistently bad after each update but noticeably worse after the current patch, where first load into hideout took around 10 minutes, and stutters continued for quite a while after.

after a while of playing with effects heavy abilities (black hole, smoke bomb, etc etc) in sandbox, games run very well and the hideout sits averaging 125-150fps on max settings
