On Windows 8.1 and Windows 10, Unreal Tournament 2004 has problem with DirectDraw.

The following error pops up:

LockRect failed: D3DERR_DEVICELOST

History: UD3DRenderDevice::ReadPixels <- UD3DRenderDevice::Present <- UGameEngine::Draw <- UWindowsViewport::Repaint <- UWindowsClient::Tick <- ClientTick <- UGameEngine::Tick <- Level Untitled <- UpdateWorld <- MainLoop

To resolve the issue you can deactivate the call for DirectDraw and use OpenGL instead.

Do the following:

Go to YourGamedirectoryUT2004SystemUT2004.ini

Find the section [Engine.Engine]

Comment out: RenderDevice=D3DDrv.D3DRenderDevice with a ;

Remove the “;” for RenderDevice=OpenGLDrv.OpenGLRenderDevice

Your section should look like the following:

[Engine.Engine]
;RenderDevice=D3DDrv.D3DRenderDevice
;RenderDevice=D3D9Drv.D3D9RenderDevice
;RenderDevice=Engine.NullRenderDevice
RenderDevice=OpenGLDrv.OpenGLRenderDevice
;RenderDevice=PixoDrv.PixoRenderDevice

Unreal Tournament should now start as normal
