[Solved] Terrible performance in Linux Mint compared to Windows (piefed.ca)

I have an older computer that I use for some simple games. Its I5-7400, GTX-1050, 12GB memory, and an SSD - not new by any standards, but most of the games I'm playing are a decade old or more. I switched to Linux Mint today, since I don't want to use Windows 11, but the performance on Mint is terrible compared to Windows 10. For example, in Portal 2's native Linux version, I get like 10 fps in the title screen. War Thunder doesn't even launch. The drivers are set to Nvidia's proprietary drivers via the GUI. Am I missing something? I'd really rather not switch back to Windows.

Edit: VulkanInfo is saying, "ERROR: [Loader Message] Code 0: loader_scanned_icd_add: Could not get 'vkCreateInstance' via..."

It also seems to only be showing my CPU, not gpu? Not certain, since I don't unstand a lot of the details, but it says, "deviceType = PHYSICAL_DEVICE_TYPE_CPU".

Edit 2: turning off secureboot fixed it.

I haven't used NVIDIA for years so I'm not much help with that, but have you tried using the Proton version of Portal? It usually works better than the native version.

Unfortunately its not just Portal thats the issue. Its everything.

Have you tried the proton version of everything?

I have for some, and had the same issues, but its solved now. Apparently secureboot messes with the GPU drivers or something. I turned that off and its working fine now.

Just a guess, you're not done the MOK, that's kind of keys used to sign modules that are stored somewhere deep in the hardware. Without them your laptop refused to load the proper modules and you was using shitty nouvea driver, so the bad performance.
