VRAM 256MB in Windows XP but 512 MB in Parallels

Hello,
following setup:
MacBook Pro 2017, Intel Iris Plus Graphics 650 1536 MB, 3,1 GHz Intel Core i5, Macos 10.13.4
Parallels 10.4
Windows XP Pro, SP 3

In the Parallels setup I configured 512 MB VRAM for the Video-Adapter and activated 3D. But the Parallels-Video-Adapter (06.04.2016) in Windows XP only shows 256 MB?

Is there any possibility expanding this to the 512 MB?
Thanks very much.

 

Hi @SvenR , please help us with the screenshot of Parallels Configuration of the RAM allocated to the Windows virtual machine.

 

Hello Arun,

thanks for your question. Attached you find files for RAM and VRAM. Perhaps the 8 GB RAM are a little bit overdose for the WinXP?!

Ups. Now, I recognize, that the Machine only works with 2,75 GB Ram? Where is the remaining ram to the 4 GB or 8 GB?
