Something is terribly wrong with Shaders since 3.27

Bump.

The game has been performing poorly for a while now. It's getting worse with each league. Currently, most visual effects disappear at random moments. I've been playing since 2013 and have never seen the game in such poor condition before. I've searched online for a solution, but I keep finding the same guides that don't help.

In juiced content my shader bar is constantly full and I get 40fps. No idea what to do, I've tried the 100gig/unlimited shaders in Nvidia control panel. Didn't help at all.

Getting the same issue in 3.28 too, major fps lag a desyncs. Shader bar in statistics just keeps jumping full and empty, even when doing the same map over and over (City Square in this case). Started happening as soon as I started running juiced maps.
