Hey, im playing modded PZ and suddenly after a while of playing i started having an issue that i never had before, fps drops to 0 constantly every 1-2 seconds for half a second or so, i tried everything from increasing the ram xmx limits in the .bat/json files up to overclocking my cpu etc, gpu usage only is stable in the menu when paused but when in game it instantly drops to 0 only to get back to 40% for a split second, also jumping like my cpu.
The screenshot attached is showing my cpu/gpu behavior when the game is running in the background, the spikes are more randomised when ingame.

#

im going to try and record the behaviour right now

Are you able to check your CPU and GPU heat as well?

#

Additionally, can you check your Applications and see if it is PZ that is using the most CPU?

it is using the most cpu, gpu/cpu temps are always around the same level no matter what games.

#

i mean i can run easily cyberpunk and dead space remake on this pc on medium/high settings stable 60fps so yeah

Different API, so not a fair test

#

A better comparison would be Minecraft for example

#

Does this happen on a new save without any mods?

#

let me test as well

#

minecraft i mean that shit can run with 380 mods on 12gb ram allocated so i dont think its an issue with that.

Test the modless save as mentioned

thorn wadi Apr 8, 2024, 10:36 AM

#

yeah its fine on modless. still the weird part is that the game run perfectly fine for over 5 hours playing with the mods and then suddenly i started having heavy performance issues. im going to be testing which mods could be the cause of the issues.

Just looks like debug mode catching errors

#

You have it enabled?

thorn wadi Apr 8, 2024, 1:12 PM

#

i tried to enable it but idk exactly where, i added the -debug to launch options

silver bolt Apr 8, 2024, 1:45 PM

#

Yeah, that is how you enable it

#

And it caught a bug, which is the job of debug mode

#

I generally recommend not having it turned on unless you are doing admin work or fixing your own mods

thats pain, i tried to see what mods are erroring out but with this happening i need to check one by one 130 mods ;-;
