Massive fps drops

[Zenithorr]

the specifications of my pc without graphics: gtx 970
cpu: i7 4790k
ram: 16gm ddr3
When entering a town everything slows down, from having 150 fps it drops drastically to 30-10 fps, it also happens when I drive, when I zoom in all the way it goes great, what happens? how do i fix it?

I'm going to try all that, thanks for your attention.

It can be pretty hard to diagnose, unfortunately, and some lag is expected depending on what your game settings are, where it's installed, and what's running on the computer at the same time.

A) Did you enable 225% and 250% zoom?
Check in Options.

When you zoom in, you have maybe 100-400 tiles to sort. When you zoom out fully, you have 2500 - 10,000 tiles. Likewise, when you're zoomed in, the edge of the map being streamed in is outside of the visual area and can't be seen, but when fully zoomed out, you can actually see the edge (on high resolutions).

So the more you zoom out, the worse performance will be.

B) What resolution did you set?
This is also highly resolution dependant. 4K will be several orders of magnitude worse than 2560 or 1080, for example.

C) Is the game installed on SSD or hard drive?
Older hard drives can have long seek times, which means when trying to load each individual chunk (5x5 area of the map), additional lag can be introduced. Energy efficient drives can be much worse, as well as drives with slow rpms, such as 4200-5200 rpm drives.

D) Do you have an antivirus?
Windows defender is -usually- fine, but can sometimes constantly check files as the game saves/loads them. Other antiviruses can be far more aggressive.

Sometimes turning off realtime protection or adding exceptions to %UserProfile%\Zomboid
saves\ can help, but sometimes they also ignore these settings.

You can sometimes work around this by adding the launch option (right click PZ -> properties) -cachedir:C:\zomboid to move the disk to C, which will avoid predatory scanning in the home directory of some AVs.

E) Do you have other software running in the background?
Check task manager for other programs using high amounts of CPU, such as Windows update. It'll sock performance mightily. Same thing with Windows Defender.

F) Are you on an up-to-date version of windows?
ZGC, the new pausless GC that PZ uses requires Windows 1803 and above to function. Check the windows build number to see if you're above this. In the start menu, type run, press enter, then type in winver and press enter again to get the build number.

G) Have you tried changing power options and GPU options? If it's a laptop, is it plugged in?
High performance is the way to go for both GPU and power management settings on Windows.

If you have an nVidia GPU, then you may find it performs better if you set OpenGL to run on the nVidia card, just in case.

If it's a laptop, some won't be able to deliver enough power to run the CPU and GPU and full power and instead split the difference, which can hurt performance. Plugging in can usually help here.

Hi, I've done everything you say and it's still the same, I can't zoom as I would like, when I'm in stealth I need to zoom more and it's impossible to go down to 10-20 fps, I hope they fix this bug, it's a great game... :(
