1). Keeping the 32 bit exe and set reducemouselag to false:
You'll need to change UT2004.ini :
[D3DDrv.D3DRenderDevice]
ReduceMouseLag=False (Game will crash in fullscreen if this is set to True)
Also recommend using the settings UseVSync=False and using MaxClientFrameRate=XX

2). Using the 64 bit exe :
(Creates a separate ut2004-win64.ini file, and it's already set to use the Direct3d 9 renderer so you don't need to change it)
- Download Unreal Tournament 2004 Patch v3369 [64-Bit Windows]
- Under [Engine.Engine] in the ut2004-win64.ini, make sure you have RenderDevice=D3D9Drv.D3D9RenderDevice as your selected driver (although this should be the default setting)
