To set a particular game to run in SWVP mode:
- First, press the windows key and the "R" key at the same time to bring up the Run dialog.
- Type in regedit in the field and click ok.
- Once Registry editor is open, click on Computer in the left pane then go to the Menu bar, click Edit and click on Find.
- After the Find window opens, type in _3dmark06.exe on the Find what field then click Find Next.
- When youve found the entry, right click anywhere in the window (on the right panel - where the _3dmark06.exe entry is listed) then select New>DWORD Value.
- Type in the name of the executable for the game or program that you are trying to run in SWVP mode but dont forget to add an underscore [_] before the first letter (ex.: if the game executable=ra3.exe, name should be=_ra3.exe).
- Having done that, double-click your newly made entry then change the default value data from 0 to 1.
- Press the F3 hotkey (Find Next) to find the next entry.
- Repeat steps 5 to 8 until you get the "Finished searching through the registry" dialog.
The next time you execute the game you just added, it will now run in SWVP mode.
To revert to HWVP mode, you can either delete the entries you added for that game or change the data value from 1 to 0.
I have also seen other configurations with ~executable.exe (ex.: ~ra3.exe) added as well for every instance of the underscored counterpart.
For now, I havent got the foggiest idea whats the reason or why this is added, but Ill be finding that out for you and will add that as Part 3 of this series. My theory is that one controls Pixel processing as well, in addition to vertex processing, as they do have unified shaders, you know.
You might want to go about this by adding the underscored dwords first then testing to see if your game has improved then adding the ~counterpart and re-testing to see what impact it has on you. I have read this has different effects on different processors since this is where youre redirecting the processing.
