Hi,
I have 2 users (out of several hundreds) which have a slowdown in playing Birth of America (100% delphi game with Omega wrapper). They both have an hyperthread P4.
One disabled the option, and the game run at full speed.
The other has not done that yet.
Any idea why these P4 can slow a DirectX app? I have them run a test app where there is only one bitmap and some D3D text displayed with Omega (DirectX 8.1) and they run it at a very low speed too. So nothing particular to my game, but more about some DirectX call being fumbled by the 2 virtuals CPU.
any help appreciated on the issue. Is this a known problem that hyp P4 have issues with Dx apps? :roll:
