Please Help - Poor Performance with 2019 16" MacBook Pro

Post by mdz777 »

Hi all. I am using Virtualbox with a 2019 MacBook Pro 16" with Windows 10 Pro. Sole purpose is to be able to play GTA V. I have not attempted to download the game yet as performance is quite poor. I have tried various system settings (memory and cpu) and tested with YouTube which is very laggy/unresponsive. I cannot upload the .log as it is too big (197kb).

EDIT 1: I have tried various resolution settings using EasyRes as well.

Macbook Specs:
2.6 GHz 6-Core Intel Core i7
16 GB 2667 MHz DDR4
AMD Radeon Pro 5300M 4 GB

Any help will be appreciated. Thank you!

If you 'zip' the log it should be reduced to an acceptable file size.

Drop VM processor count to 2. More cores make a VM run slower (though perhaps not as slow as you're seeing). Only increase if your added VM app is multi-threading and runs both cores 100% all the time.

Also see 63BottlesOfBeer's speed solution here:
viewtopic.php?f=8&t=90446&start=75#p470879

The Virtualbox video cards may not handle 4K screen sizes. Also, games in a VM may not work well. Try a video benchmark before dropping money on a game.

63BottlesOfBeer's solution (viewtopic.php?f=8&t=90446&start=75#p470879) no longer works in macOS Monterey. The "Open in Low Resolution" checkbox has been removed. Instead you need to edit the file
/Applications/VirtualBox.app/Contents/Resources/VirtualBoxVM.app/Contents/Info.plist
as admin user and change the line

Code: Select all

<key>NSHighResolutionCapable</key>  <true/>
to

Code: Select all

<code>NSHighResolutionCapable</key>  <false/>
For example:

Code: Select all

$ cd /Applications/VirtualBox.app/Contents/Resources/VirtualBoxVM.app/Contents
$ sudo vi Info.plist
mod edit: this change and workaround has been added to the "63Bottles" solution.
