Play MOOM on 4K Ultra-Nightmare. It's actually pretty good.
Other than that look into emulators with Vulkan renderers. Nshittia's Vulkan support may be inferior to AMD but you've got a fucking 2070 so you should be able to handle RPCS3 just fine.
Or you could sell it and get a Vega/5700 to join the linuxgaymen master race
