Hello There,
i still have problems with my VirtualBox Performance and after using a native windows on a second harddisk, which really sux a lot, im trying to get VirtualBox to get fast again.
First of all, i have an AMD FX 8150 CPU (8x3,6 GHz), 16GB of Memory and an AMD Radeon 6670.
I create a new Virtual Machine with the following Settings
- Operating System: Windows 8.1 64bit
-- VT-x/AMD-v Enabled
-- Nested Paging Enabled
- 4 Cores
- 8192MB Memory
- 2D + 3D Support Enabled with 256MB GPU Memory
Guest Additions are installed
And if i run a very simple Game which uses 2D Acceleration, it extremely laggs. Screen and Sound are all stammering and its completely unplayable.
There are the recommend specs for the game
- CPU (Single Core)
-- Recommend: 2.66 GHz
- Memory
-- Recommend: 1GB
- GPU
-- DirectX 9.0c capable GPU
If i run the game on the Native Windows, i can start it about 16 Times and still play it without any lags, how can it slow down that extreme in VirtualBox? And its not just this game, i tried a lot of simple 2D Games and even the RPG Maker is not capable of doing simple games without starting to lag.
Watching Videos is impossible, even if they are far from FullHD
And its not just Multimedia, if i run a plain CPU Benchmark i get like grades from 10 years ago
Do you guys have any idea how to speed things up? I mean, that way Virtualisation is completely useless at all.

I tried to install the Catalyst Driver to check if the proprietary Driver is better doing this --> the opposide. The VM is even much slower, unuseable now, sometimes there is a 3 seconds freeze and everything is like on an 8 year old Computer.
So it might be related that both of the Drivers for AMD Cards are kinda bad...

can you try with a linux guest ?
I use also virtualbox, with linux guest ( archlinux i686 ) the performance is correct, 3D acceleration is Ok ( checked with glxinfo and glxgears from the mesa-demos package ),
I use an amd radeon hd4650 pci with the radeon driver ( open source driver ),
I think it's normal to see lower performance with windows guest, because the host is linux, so it is more difficult to have optimal performance when the host is too different from the guest
