Been trying to use Vulkan on Linux mint 20.1 and it will not run . If I use "prefer Best" it still won't run but if I use "Basic" no problem . Linux mint is built on Ubuntu and is compatible with it. Any thoughts on this ?

Hello,
Same issue for me.
Laptop i5 - 2 GPUs Nvidia1650/Intel with dual system Linux/Windows.
On Manjaro or Mint/Ubuntu : Advanced & Prefer Best don't run ! so I use Basic in Tier1.
On Windows, all run ... but more slower than Linux !!!!

maybe a problem with driver, mesa under linux ... or not.

One question to tier2 users : if it's possible, how choose renderer in tier 2 ?

thanks.

in Core.cpp, inside function _tWinMain at the bottom of the file in call to agk::InitGraphics, set AGK_RENDERER_MODE_PREFER_BEST (Vulkan then OpenGL) or AGK_RENDERER_MODE_ONLY_LOWEST (OpenGL)

Remember that under linux you need to install the proprietary graphics card drivers to get the best performance out of it.
Especially when it comes to Vulkan support.
I don't know if you have already done that.

The test I did was to move a cube from 1 side of the screen to the other at full screen. I'm away from my computer at the moment but will replicate the test later and we shall see. I set the frame rate to 500 in both studio and classic. Classic produced about 150 fps whereas studio was about 400. The cube was set in a continuous loop. I will carry out the test with vulkan and openGL.
Does this sound like a viable way to test.

Pfaber1, if you have a Nvidia GPU, here is the solution that works for me.
you build your prog with #renderer "Advanced"
and you run it in terminal with : __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia ./TheNameOfYourProg
Et voilà !

And the last but not the least, in your terminal in agk folder...
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia ./AgkStudio64
you run studio with vulkan activated and you launch your prog under basic, advanced and prefer best, as you want.
