Premiere Pro 24.5 Preview lagging all of a sudden

[fantastic_leader0D45]

On nvidia 4070ti and intell i5 11400 with 32GB memory. Latest drivers

Since yesterday, my preview has been abysmal and can't do basic editing anymore. Switching to studio drivers do nothing. Im already using ProRes proxies. I rolled back to 24.0 and there's little to no improvement.

Please help

What changed about your system, or your project, since yesterday?

@Bruce Bullis nothing i can think of worth mentioning. i installed/reinstalled intel wifi drivers if that's relevant. i meant i first experienced the issue yesterday. It used to be really good

update: turning off proxies made it much more smoother. what could be the cause? 

[Bruce Bullis]

Proxies would be my primary suspect. 😉 

What's the codec and format of the non-proxy media you're using?

[fantastic_leader0D45]

HEVC 4:2:0 
MPEG Movie / .mov

I'm weirded out because i assumed proxies would make everything faster

That's definitely the hope, though (as you've seen) that's not always the case.

Okay whats the reason for it doing the exact opposite of what its supposed to do and how can i fix it? Thank you
