Vulkan on older intel CPUs (on manjaro) (lemmy.blahaj.zone)

I'm trying to run Godot 4 with the Forward+ Renderer on an older Thinkpad (T420 i5 2520M). So far I've installed vulkan-intel, lavapipe (vulkan-swrast) and vulkan-ultis for vulkaninfo. Now I don't get the "missing drivers" errors anymore, but now it just crashes. The console output is this:

handle_crash: Program crashed with signal 11
Engine version: Godot Engine v4.2.dev3.official (013e8e3afb982d4b230f0039b6dc248b48794ab9)
Dumping the backtrace. Please include this when reporting the bug to the project developer.
[1] /usr/lib/libc.so.6(+0x3e710) [0x7f0529df1710] (??:0)
[2] llvm::CmpInst::getInversePredicate(llvm::CmpInst::Predicate) (??:0)
[3] [0x7f05140264c0] (??:0)
-- END OF BACKTRACE --

Is vulkan just not supported for older intel CPUs, or am I doing something wrong?

I actually did that before, but that ended up breaking a bunch of stuff. When running vulkaninfo for example, it gives me this output: /home/smorty/.cache/yay/swiftshader-git/src/SwiftShader/src/WSI/VkSurfaceKHR.cpp:246 WARNING: UNSUPPORTED: pSurfaceCapabilities->pNext sType = 1000111000 /home/smorty/.cache/yay/swiftshader-git/src/SwiftShader/src/WSI/VkSurfaceKHR.cpp:246 WARNING: UNSUPPORTED: pSurfaceCapabilities->pNext sType = 1000239000 Speicherzugriffsfehler (Speicherabzug geschrieben) (that's german for "save access denied, memory dump written") So yeah, that seems to not work unfortunately.
