[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.

Secure Boot can sometimes mess with it. Try disabling that in your BIOS.

This seems to have fixed it! Thank you!

The most current NVidia driver generation needs special setup for secure boot. But IIRC it doesn't support the non RTX cards anymore. And sadly I can't remember how to set up the older generations.

For the newest you need a setup that compiles and signs the Kernel module of the driver and you also need to manually import the (generated) key into your UEFI to allow secure boot to succeed. The former is usually mostly automated by your distribution, but the latter need to be done by you manually.

Or, just disable the increasingly inaccurately-named "Secure Boot."

Yeah, that's always an option. If you want to. On paper I like the idea for security reasons, but I dislike that a single company can basically control, what is able to be installed/executed and what is not allowed.

It's always something-something-Microsoft
