How to properly change launch options for best performance.. help needed aha

[Ryohei]

I'm not very PC savvy but I wanted to try and improve my performance and handle those massive screamer hordes better. Browzing the performance sticky I came across the follow tips.

add to launch options: -force-d3d11

but when i do this all I have is a pink screen on starting 7days2die so its probably not the right one for my PC so what do i try now.. is it: -force-d3d9??
and are there other launch options to use and how to I put multiple ones in the option bar.. seperate by a comma or a space or no seperation.

Again any advice appreciated!

found this as well will it work for me in a13? About to see what forcing d3d9 does to performance b4 trying the rest.

Jaga:
“A11 has some latency issues with disk reads/writes. Causes mild stuttering. Defragging the disk can help, uninstalling and reinstalling can help. Putting the game on a fast SSD or RAMdrive can help.”

Try this if you want too as well

Madman:
“Uninstall the game through Steam, then close Steam
Find the 7DTD install folder "\Program Files (x86)\Steam\SteamApps\Common\7 Days to Die" and delete it.
Edit the registry with regedit, find the "HKEY_CURRENT_USER\Software\The Fun Pimps\7 Days To Die" key, click on it and delete it.
Run a tool like CCleaner to get rid of temp files, DNS entries, etc.
Find "ClientRegistry.blob" in Steam's folder (\Program Files (x86)\Steam), rename it to "ClientRegistry.blob.old"
Restart the computer
If you don't have any saves you care about, delete the "\My Documents\7DTD\" folder (or move it somewhere else like the Desktop)
Start Steam and reinstall the game

Once these steps are complete, force DX9 in steam:

Library> game> properties> set launch options> type in: -force -d3d9

Go into your video card control panel, and disable Vsync for 7 days to die.
