Direct3D

Summary

What is difference between classic wine and wine enhanced with Nine support? The answer is simple - performance. When we play most DirectX 9 games, we want the highest performance possible. Sadly, wine loses a lot of Direct3D9's speed through the inefficent translation of HLSL and D3D9 calls to OpenGL.

Benefit to Fedora

All games wich using Direct3D9 (most of games which wine can run) will have very very good speedup. Real numbers?

  • On a simple demo with a weak CPU (Athlon TK-55 X2) CPU usage dropped from 20% to 10%!
  • Need a benchmark? 2014-09-14, with older DRI2
  • For real games, we're getting mostly double the framerate (depends on the game, the driver and the card)
