Very poor performance on high end pc after Premiere Pro 25.2

@Alexander_DVA i updated the PSU, bought a Corsair RM1000x but i'm still having all the same problems. My old PSU is on my brother's PC, which is older and less powerfull than mine and he doesn't have those issues. I'm really out of options now. Today i updated to 25.5 version. Did all the tests possible to check again the PC's health, everything is how it should be. Did a CPU and GPU stress test together to really stress the PC and it was ok

I cant give you a direct recommendation - but there are great review sites like toms hardware, that have "Best Power Supplies 2025" listings

@Alexander_DVA do you have any recomendation for new PSU?

For the crashes i can only second what was written by others in this thread - your power supply is known to have caused problems (if you saw the youtube review where it caught fire during a load test) - so if you invest into new hardware i would put the power supply above all else and pick a brand that is "known good" and has passed reviews 

@Alexander_DVA thanks for the replay. I'm about to buy a new RTX 5070 ti, but i'm already using proxy work flow. It improve the stutter issue, but doesn't help me from crash.

Thank you for the update - the file format you are using is only fully hardware accellerated with nvidia 50xx series. On older systems this probably requires using a proxy workflow - which should remove the bulk of the processing cost for your system and makes it even easier to work with than your other formats.

@Alexander_DVA yeah, i did uptated the software. Most of my problems happens when i'm editing raw files from a Sony FX30, when I edit videos from iPhones, and other medias, i don't have much problem, but in my actual work, we use the FX30 to record the videos, so everyday I struggle with the software. 

@Fontenelle Moraes have you updated to 25.3? there were a lot of performance related improvements in that release

Guys! Please! I can't take it any longer. Everyday my problem is worse. I'm working in a project with 8 videos but, every little change i do in the videos, premiere freezes, stutter or crash! This is one of the worst experience i ever have with a software.

Thanks @Amal MP  I don't know that Autokroma Influx but i'm sure I can learn it from internet. I'm experiencing the exact same problems, every day with every project

@MyerPj  this is the proxy configs I'm using
