Game crashes with latest version 15.1

[Mromerolillo]

I just tried the latest version of the plugin, and all the games crash as soon as I launch them.
I followed these steps:

• I unpatched the game with the previous version of the plugin.
• I uninstalled OptiScaler through the plugin.
• I uninstalled the plugin.
• I installed version 15.1 and the OptiScaler setup.
• I pasted the installation command into the game properties.
• I launched the game, and it crashed.
  Tested on Bazzite. Proton-ge 10.34

What am I doing wrong? I'm stuck on version 13.0, with this version the plugin works perfectly! it's the only one that works for me!

Is the game installed to a separate drive or sd card?

I’ve got the same problem.
Various games crash on launch if I use the latest versions of Decky Framegen (E33, Cyberpunk, FF16, etc.).
I can’t figure out why, but I really wanted to use the new FSR4 int8 4.0.2c.

It must be something to do with how the Optiscaler plugin is installed, because if I install it manually it works perfectly! You can always download it from the Optiscaler Github!

I know, I’m actually installing it manually, but it’s a real hassle on SteamOS.
Even the Decky DLSS Enabler hasn’t been updated yet with the new FSR4 int8 4.0.2c

I’ve found, however, that in many games you just need to replace the FSR file with version 4.0.2c and FSR4 works automatically without Optiscaler.

It only works in games that natively support at least FSR 3.1, and it’s handy if framegen is already supported natively.

I went back to the former Decky- Framegen version since I also had a few issues with crashes on various games when using the newest version on the SteamDeck.
