(Sorry if this issue is a duplicate, but i searched the whole internet but found no answers.)

Your system information

• Steam client version (build number or date):
• Distribution (e.g. Ubuntu): Ubuntu 24.04
• Opted into Steam client beta?: No
• Have you checked for system updates?: Yes
• Steam Logs: logs.tar.gz
• GPU: NVidia GeForce GTX 1050 Ti

Please describe your issue in as much detail as possible:

i expected stable 60 fps but got ~6 fpm. I tested Vulkan, it works. I reinstalled my 550 NVidia driver with 32-bit compatibility and this issue still exists. Also, Steam doesn't detect the GPU:

vkEnumeratePhysicalDevices failed, unable to init and enumerate GPUs with Vulkan.
BInit - Unable to initialize Vulkan!

Tested Games with this issue:

• Black Mesa (Necro Patch with no DXVK, fps is ~2)
• Half-Life 2 (OpenGL, Vulkan crashes for no reason)
• Half-Life 2: Update
• Half-Life 2: Deathmatch (fps is ~10 with big stuttering on movement on low graphics with lowest 16:9 resolution)
• Transmissions: Element 120 (Sourcemod)
• Counter-Strike: Source
• Half-Life (OpenGL fps is ~20 with big stuttering on movement, Software mode renders fine)
• Half-Life: MMod
• Sven Co-op (fps is ~20 with no stuttering)

Steps for reproducing this issue:

1. open steam
2. run any Source Engine (or even Goldsrc) based game (Except Jabroni Brawl: Episode 3 because it works)
3. experience IMMEASURABLY HUGE LAG (average fps: ~0.1, which is 10 seconds)
