[PoE 2] Low CPU/GPU usage and FPS in Towns and certain areas

hi guys probally the issue with all of you is because you are running RAM with just one stick or dual channel (xmpp) is not propelly enabled in BIOS

also, poe1-2 wont use 100% of you cpu no matter what because they will focus process on first 2 cores and calculate secondary stuff to the rest of them

but generaly when you get low cpu/gpu usage but still low fps its because RAM is not working fast enough to send information to the cpu. took me years to realize how it works, make a good use of this information.

cheers

Cpu usage: 40-50%
GPU usage: 60-70%
Whenever I engage in crowded mechanics (breach/exp/shit map laouts) my fps drop to 50-60s from 150-250fps. I have no problem when there is no crowd (campaign, nojuiced maps etc)

I didnt have that much performance issues in the first few weeks but maybe that is probably our maps were not juiced and we were playing ruthless.

I will never understand how a company makes an exact clone of a game with HORRIBLE performance issues. This is just like poe1 all over again, just disappointed.

If you see your CPU going from 10ms to 17ms, it means it is taking that much longer to process a single frame. You can have a million cores and threads, but the slowest of the threads dictates how fast the frame is completed and sent to the GPU.

If you have one core at 100% and rest at 40%, then the main thread is getting choked - get a faster CPU or accept the performance. Outside of the few X3D/4090 gamers in the thread, most of you are running 10 year old CPU's. While yea it's the minimum spec, you are not going to get anything mindblowing without dynamic resolution, I would assume towns are at most 1080p30. Anything past that would be a cherry on the top.

The only good metric to see is if one CPU core is pegged at 100%. If yes, that's what you get for performance. Don't use overall utilization in diagnosis (unless it's 100%, that's a different issue).

Also, a game using 100% of CPU means your OS has nothing left and if the OS is programmed poorly, you get a hard lock or shutdown; see the 2 megathreads already.

This is a GGG classic shader+audio issue, if you record your gameplay with F1 menu with the bars visible, you will notice your Shader bar pegs to 100% when you get lower performance -> eats CPU -> lower FPS. Also you will get some audio drops or delays with screen freezes.

It's a side effect of realtime shader compilation to prevent cheating software from reading precompiled shaders to find out if something like a randomly spawning boss or a rare monster modifier is present. Downside is that when you meet something new, the game wants more shaders and gosh darnit will it takes its time to generate them.
