Visual Studio performance

This post was originally published on this site

I am trying to use Workstation Pro 15.5 to run Visual Studio 2019 in a windows guest, and the performance is pretty abysmal. It appears that hardware accelerated graphics is working fine for the OS, but Visual Studio is noticeably laggy and sluggish. Disabling 3d acceleration for VS improves things somewhat, but it’s still crummy. As a rough kind of benchmark, I can open a code window on a native windows machine and scroll and see that it is fast and smooth, and CPU utilization is basically 0%. In the VM with 3d enabled it’s very rough and stuttering, and CPU utilization is 30-40%. With 3d disabled in the VM it’s less rough but still laggy, and CPU utilization is 20-25%. I’ve never received any errors, just poor performance.

 

Host:

HP Z4

i9 10980xe (18 core)

64gb ram

Quadro RTX 4000 (8gb)

Ubuntu 20.04 (5.4.0-42-generic)

Workstation 15.5.6 build-16341506

 

Guest:

Win10 2004

4 cores, 16gb ram, 2gb video ram allocated

VMware SVGA 3D driver 8.16.7.5

 

I’ve tried updating the NVidia driver to the latest (450), reinstalling VMWare Tools, I’ve swapped in different GPUs (an NVidia RTX 2080ti, and an AMD Radeon 5500xt), and I’ve tried various combinations of core counts, ram allocation, etc. Anything more than 4 cores seems to magnify the problem, but otherwise I haven’t seen any change. FWIW, anything based on Chromium (Chrome, Atom, VSCode, etc) seems to have the same problem. Other Windows apps I’ve tried (eg, Paint 3d) run fine.

 

Is this a known issue with Workstation? Is there anything else I can do to troubleshoot it?
