Hi I think my system is not allocating enough RAM to WINE applications . I am using WINE to play games but they are loading slowly and RAM usage is normal. So how can I improve reserve memory of WINE?

I don't think there is much you can do as wine takes what it needs. As it is 32bit the upper limit is 4Gb. Then there is a 2Gb (sometimes 3Gb) limit for RAM per application.

Video RAM (VRAM):
You can allow more VRAM by editing the wine registy:

  1. wine regedit
  2. go to:
    HKEY_CURRENT_USER → Software → Wine → Direct3D → VideoMemorySize
    and set the value to a higher one. The default seems to be 64Mb.
    If you see no such key, create it (right-click on Direct3D, select New then String Value and name it VideoMemorySize).

More registry information: useful registry keys from

This detailed memory management page from the wine developer notes might give more clues but it is quite technical.

Try adding the Direct3D folder, then create the key. Then close all wine applications so the wine server does not run. What wine version are you running? (wine --version) – rosch Oct 20 '12 at 17:41
