So, I will try my luck here hoping I can get some pointers.

I have a GTX1050Ti that is four years old, and I just updated my system to Ubuntu Studio 20.04 with NVidia 470.103 driver. Previously used Ubuntu Studio 18.04 with an older driver, and everything basically worked fine. But since some games started to refuse to work at all (Surviving Mars) or switched their default renderer to Vulkan and became unplayable with both Vulkan and OpenGL subsequently (The Long Dark), I told myself I better update my system and drivers. It can only get better, right?

So now with the updated system and drivers I am basically facing the issue that when using Vulkan, I have micro-lags of about 1/4 of a second every few seconds in every game that uses it it seems (tested The Long Dark and Dirt 4). I have the same issue when using the NVidia 510 driver by the way. When I switch back to OpenGL in The Long Dark for example, I get other kinds of lags that make it unplayable as well.

So while some of this is certainly game-specific, I get the impression anyway that most games move to use Vulkan, which does not properly work on my card, although the card is fairly recent and using the latest proprietary drivers.

What can I do here? Are there any ways to tweak Vulkan or my drivers to make it run decently? Or am I just out of luck and need to get an AMD card?
