My Setup:

  • Sony Vaio VGN-FW11E with Radeon HD 3470 (tech spec)
  • 3 GB RAM
  • Ubuntu 12.10 64bit

The Problem:
After a few minutes of gameplay the game is going down in speed to very slow. After quitting I see a RAM usage of 1,6 GB and a cache of 1,4 GB. After a fresh restart the Ram is only at 700MB and Cache around 100MB.
My idea is to split the memory hardcoded between CPU and GPU (see Raspberry Pi Project) so the Cache and the GPU are not in conflict. But it's only a "maybe it will help" Somebody has an idea about why this happens and how I can speed it up?
Is there any slow down between the wine 32bit (1.5.x) application and the 64bit OS?
