   WHY MY GAME RUN DIFFERENT :(
  My Game Run on this machine , all programmes are all right ... but on another machine, which is less power than this one , run more fast ... several tests said that this is caused by hardware ( this machine re-install an os XP which was 2000 before now. ) Any one knows sth about it ? I can't find the answer ...   
  Can you show us the code that sets the speed of your game, so we may check it?   ;  You're going to have to provide us with LOTS more information before we can give you any useful ideas!!Quote:From the Posting guidelines:Include all the information that might be needed for people to give a good answer, including the version of DirectX you are using, as well as the SDK version, and any details about your hardware that you think might apply to the problem. If you don't give enough information, people won't be able to help you until you do.If you want to post any source code, please try and make it the relevant parts - and surround it with [ source ] tags.hthJack   ;  I would suggest background tasks your computer is doing is probably effecting performance if it's a more powerful machine.Also it depends if you have the developer version of the runtime on versus the retail, and if it's set to debug mode or not.Here's a tool you may want to run to see what is running on your machine:Hijack this.  As the page suggests it's best to decent run automated anti-spyware and anti-virus first though.You say you run several tests that proved it was the hardware?   ;  All dx-components are retail version ... I felt the main cause was timeGetTime() on different machine ? and i post in the 'for beginners' to collect implements I'd like to post my code, but still i don't know which part cause the different... post thousands of lines , that's no meaning ... and only a window with static picture ...with no comparation can say anything ...I'll try my best find ...well, is there anything tool to testify that it is truely a 60FPS mode ? ;  Sounds like VSYNC to me.   ;Quote:Original post by BoderSounds like VSYNC to me.Sounds that way to me as well.   ;  By the way, what 'VSYNC' is ?   ;  http://en.wikipedia.org/wiki/Vsync   ;Quote:Original post by littlewaterBy the way, what 'VSYNC' is ?You can try to enable/disable it by setting up the D3DPRESENT_PARAMETERS::PresentationInterval field before you create your device.However, most Nvidia/ATI drivers seem to have an "override" option - so you may have to check the settings in there if the code appears to do nothing [smile]hthJack
