Win7: Enabling HPET
Hello,
I would like some help to understand a few things about win7+ HPET and Bios+ HPET. To start it was my understanding that if you enabled HTEP in the bios win7 would automatically be using HTEP. However, I'm reading that it does not and will still use the Time Stamp Counter (TSC). So I'm not sure what point it would be enabling it from the bios.
2ndly, using the command bcdedit /set useplatformclock true (then reboot) is said to enable HPET using Win 7. While bcdedit /deletevalue useplatformclock (then reboot) is said to remove it. To test to see if it's working or not you have to use either:
A. Timer Function Performance (run the program before and after the tweak to see if the QueryPerformanceFrequency() freq value increased or not)
B. WinTimerTester_1.1 (from UncleWebb to see if you have a 1.0000 ratio at or near 100 seconds)
To see if it improves anything or not. From Unclewebbs post he addresses the use of SetFSB. From another point of view it helps improve slow connections when using this application from here.
Should we be using Win7's HPET or stick to TSC for everyday use and gaming?
