Ok this is an issue that bothers me for a long time and it's still not fixed.
When you use the AMD Vulkan driver on Windows while having vsync on I still get tearing.
I tried to talk to various developers who said that the issue is a driver issue and specific to dual GPU laptops.
I also got an Intel UHD 620 GPU and it does not exhibit visible tearing when I force games to use it.
The tearing is really visble and horrible to look at.
On Linux with the RADV driver and even with the AMDVLK driver I dont either dont notice the tearing or it's not there.
I also opened an issue on the AMDVLK github repo here : V-sync broken on dual GPU laptops · Issue #182 · GPUOpen-Drivers/AMDVLK · GitHub
Please if there is something that I could do to fix it please tell me.
