  1. Performance guidelines?

      maybe some profile tools are good friends.(Pix, Intel:GPA,  NV:Nsight,  AMD:Perfstudio)     in our project, the DP count and PS shader always hurt us.
  2. it seems that the only way i can do some things for this is to update my driver! i will try! thanks for your attention!
  3.  I found a strange phenomenon of my GPU, follow list are what i do:   1. open my video game window normally 2. look at the core clock and load of my gpu with GPU-Z, it's 810MHz and 60% load, nothing unnormal 3. minimize the video game window for a long times(>0.5 hour) 4. look at  the core clock and load of my gpu with GPU-Z, it's 60MHz and 100% load, it's uncommon 5. restore my video game window, because of the unusual state of gpu, my fps is so low, about 2 to 5 6. the gpu can't restore normal state until i close the game window and run again   my machine: OS: windows XP sp3 CPU: intel i5 GPU: Nivida GT630 GPU Driver: 301.68 DXSDK version: August 2008   i don't know why? who reduce the core clock of my gpu, the driver or d3d runtime? any idea about this? thanks! sorry for my poor english
