Virtual Machines running slow with audio stutters.

Question

Hello, I have Virtual Machines and they have been running really slow with audio stutters. I have tried both VMware and Virtual Box but the problem still persists. I do have SVM Enable mode on enabled in the UEFI Bios and I have done things like disable Hyper-V which didn't make a difference. I have pretty powerful hardware too so I know it isn't a hardware limitation. The VMs have plenty of ram and CPU cores too.

Specs:

Ryzen 7 7800X3D

RTX 4070 TI

and 32GB of DDR5 6000mhz.

***moved from Windows / Windows 11 / Performance and system failures***

Hello

Thank you for posting in Microsoft Community forum.

Given your powerful hardware, it's unlikely that the problem is due to hardware limitations. Here are a few suggestions that might help resolve the issue:

Check for Driver Updates: Ensure that all your drivers, especially for your audio and graphics, are up to date. Sometimes, outdated drivers can cause performance issues and audio stutters.

Adjust VM Settings: Try tweaking the settings of your virtual machines. For example, you can allocate more CPU cores and RAM to the VMs, but make sure not to over-allocate resources from the host machine.

Disable Unnecessary Features: In both VMware and VirtualBox, there are features that might not be necessary for your use case and could be causing performance issues. Try disabling features like 3D acceleration or nested paging.

High-Performance Mode: Ensure that your host machine is set to high-performance mode in the power settings. This can sometimes help with performance issues.

Network Settings: Sometimes, network settings can cause issues. Check if there are any network-related settings in your VM software that could be causing the stutters.

Audio Settings: In some cases, adjusting the audio settings within the VM software can help. Try changing the audio driver or adjusting the audio buffer size.

Hello there, I have tried tinkering with some settings and nothing has really changed. It is a vm with 2 cores and 2GB of ram which is more than enough for this Windows XP vm. I have also tried reinstalling Windows on the host machine in the past but that didn't do anything either.
