bought a new gfx and fps seems worse?
bought a new 3080 and after installing it, my fps seems to be worse. I have uninstalled and installed the drivers, as best I can tell, it installed correctly. I've tried changing setting in the game like skybox and vsync... any ideas?

What are the rest of your computer specs?

Fps are not only base on graphic card.Number of ram you got the Hz of your ram.Cpu you got and the hz of it.Your HDD or SSD.When you got low fps its doesn't mean its come from GC.A good system is a well balanced system.If you got bottleneck somewhere its will cause this kind of problem.

FPS problem can come from software too and not the hardware itseflt.The first thing we need to know in order to help you is what is your system spec which would include your GC-Mem and what kind.CPU and what kind.HDD or SSD?Power supply?

Then when you installed your driver did you completly delete the old one?

Did you verife file with steam?

Do you have the same problem in any other game?

When you are ingame if you open task manager and switch to the windows where its show every graphic or everything working.Is there anything at 100 % load?

What kind of sound program are you using because sometime hz using by sound and those ingame can create issue that cause lag.Some game will only fine using 44000 16 bit for example which if i recall right are those by default.

I have an intel i7-8700, 16g of RAM, I have a HDD. Power supply is a 750 i think. Task manager shows with game running about 39% CPU and 56% memory. I'm not completely sure if I completely uninstall old driver. I use Nvidia Geforce experience for my drivers, it shows the new card in there... not sure what else info you want.

I upgraded from a 2060, the game just feels like lower fps which seems odd.

I am using voice meter banana for sound... think its set to 48kHz

Game is very CPU intense, I sincerely doubt you're gonna gain much improvement from a video card upgrade unfortunately. Up to a certain point you're going to bump into limitations of the game and the CPU, which the CPU is going to be strained a bit harder now having to supply a 3080.

Are you sure the FPS is worse and not just similar to your experience with the 2060? Are you using the same settings as before or attempting to push the game further?

same settings

As much as you probably don't want to hear this, I think you're bumping into a CPU bottleneck at this point. I actually also have an i7 8700 and a 2060, with slightly spruced up settings and found the game heavily stressed 1-2 cores of the CPU while the CPU usage reported as being low. There is very little I can do to the settings that changes the usages.

It's also pretty clear when driving a car or when tons of zombies are on screen that the game itself buckles down under itself at times which can't often be brute forced with better hardware.

I think 1 of 2 things can result in lowered performance.

Either A, you are pushing your CPU even harder with a better GPU or B, you might need to run a program called "Display Driver Uninstaller" or commonly as DDU

After doing a clean uninstall of the driver, get a fresh up to date one directly from Nvidias site instead of relying on Geforce Experience.

Yeah from what I've read, the game is more heavily influenced by CPU and gpu is not has high demand. I plan on updating my PC more, but it just felt odd that a new gpu would perform worse lol.
IndustryStandard Jan 19, 2022 @ 6:25pm 
CPU is technically working harder to supply information to the GPU so it wouldn't technically be shocking. But I still recommend trying a fresh set of updated drivers.
I would also recommend updating your drivers.

Backup your game saves, and try reinstalling if you're desperate.

Honestly though, the game isn't well optimised (on a technical level) and having just a few too many items on the floor in a small space docks my FPS at 40.

Depend on its ram,he said his cpu was in the 50% use didn't talk about the ram tho.If the ram doesnt have the same hz of its cpu,ram will bottleneck the flux of data trought CPU in both direction.Example if you have cpu at 3200hz but ram are at 1600hz.Your cpu will calculate at 3200 but the data transit will only be at 1600hz so half the cpu power.Basicaly he said his cpu was a 50% so i would like to know the HZ of its ram ;)


An other thing you could try is to look at your audio setting and make sure you are using 16 bit 44100 Hz CD setting as a test and see if its hurt your fps.I had some micro freeze because of my audio program and i had to turn it off while playing PZ.

I gonna lag Hard only when in Lous
probably cuz by lot zeds and I play while mining coin and the game literally consume little amont of GPU like Minecraft
Got something else like miner It much easier to check how much Game eat GPU
Highly sugggest SSD If ya wanna upgrade

Dude, no disrespect but literally nothing in your comment is accurate at all.

As it's such an old game single threaded performance is also really important. i have an i6 6600k @4.6ghz (along with 16GB ram) and the game runs well over 60fps constantly with everything on (1080p). My Gcard is only a 1060 6gb as well. If running at higher resolutions though then it might put a huge strain on a cpu.

The only reason your FPS would be worse with a beefier GPU is bottleneck.
Such as GPU requiring more CPU, so it has less processing power for PZ, which is heavily dependant on CPU, rather than GPU.
