  I have/use VM's as my primary desktop (my host is ubuntu 22.04 or windows server 2022 and 2019).   I am a *VERY* heavy multi-task worker and have numerous applications and VM's running.   On a single VM I have the screen spanned across 5 2560x1440 displays (in vertical mode) so 7200x2560 resolution to the guest (s).  Even with 8GB of sVGA memory I see issues where not everything can be stored in shared graphics on the guest.  It's close, and depends on the applications I'm running.   Does anyone know if you can override this to the guest to provide more sVGA memory? Second but related question.  Since this is 'shared graphics memory' on the guest, I am assuming here that this is stored in the host's RAM and not directly mapped to the Host's GPU?  I.e. the host may map this to the gpu at a later point but, the guest/hypervisor stores this in the host's main memory? Reason why I'm asking this is, IF the hypothesis is true, would changing the host hardware to use a platform that has more memory bandwidth help in performance for graphics on the guest?   i.e.  Opposed to a consumer platform of 2 channel memory, going to a server/workstation platform with 4-12 channel memory help here?  As the memory bandwidth would be greatly increased.   Has anyone done any testing with this?

  I am looking to replace my aging workstation (intel/nvidia) with a newer system and am pretty much looking at AMD threadripper & Radeon graphics as it appears AMD has the best value offerings.   However I use my system to run VM's and use Linux (ubuntu 22.04) and windows (server 2019/2022) as the host OS's about equally. I am concerned as from the vmware documentation it appears that linux + radeon is not supported (functional) at all: https://www.vmware.com/products/workstation-pro.html "For Linux hosts, AMD devices are not supported" and Radeon is barely mentioned here in the forums or on https://docs.vmware.com/en/VMware-Workstation-Player-for-Linux/17.0/com.vmware.player.linux.using.doc/GUID-EA588485-718A-4FD8-81F5-B6E1F04C5788.html with Intel/Vulkan given the main mention as apparently an afterthought.  Can anyone chime in here as to what the status of support is for workstation pro for Linux & windows hosts and getting D3D/OpenGL acceleration for guests?  I really don't want to switch to using different products (like Hyper-V for windows and kvm or virtualbox for linux).   

One of the primary items I am looking for in virtualization software is to be able to run games in VM's.   Up to now this has really been limited to just older games (DX9 basically as the 10.1 support in WS 15.5 was not complete when I tested and thus skipped WS15 for upgrade).   I am hoping that there are others here that can share their experience with Workstation 16 and DX11 games.   Any issues?   Performance hits?    What about higher resolutions (1k, 2k, 4k gaming)? I know DX11 is still not the best (seems vmware is about 10+ years behind technology) but it's a far cry better than DX9.
