I'm not sure it's worth the effort though. >VirtualGL works great for OpenGL acceleration, but if you're game >requires Vulkan then you're probably out of luck as it does not seem >possible to write a VirtualVulkan equivallent at this point: >https://github.com/VirtualGL/virtualgl/issues/37 Thanks again!

I won't bore you with details about what I need this for though. :-) Thanks for the, as always, timely insight. cgf _______________________________________________ shifter-users mailing list shifter-users@lists.devloop.org.uk https://lists.devloop.org.uk/mailman/listinfo/shifter-users
