WCG and GPUGRID resource sharing...

[Snow Crash]

I started replying in the PIE thread but now just looked at your machines on GPUGrid directly. It might sound like I'm repeating some of the settings you already have but I'm just trying to be comprehensive for the next person who might need to know ...

Example 1: The new version of the GPUGrid linux app (6.12) runs differently than it had in the past.
http://www.gpugrid.net/forum_thread....rap=true#19362
Add SWAN_SYNC (yes to a linux box) and run 99% of the processors.
BOINC has no idea what SWAN_SYNC is so has no way to account for it.
You need to tell it to leave one alone so the app can grab it for itself.

Example 2: I can almost guarantee that your SR2 Win7x64 running 260.99 drivers is downclocking while you are not looking. The reason it goes up when you are watching is because it becomes "active" in 3D mode and steps down again as a power savings (go ask nvidia). I used a modded inf for the latest quadro drivers and am no longer having downclocking issues. You can also step back to your 258.xx drivers, like your 920 HTPC is (which is why that machine is returning decent results), and the downclocking should stop.
Again .. add SWAN_SYNC (yes to a linux box) and run 99% of the processors.
BOINC has no idea what SWAN_SYNC is so has no way to account for it.
You need to tell it to leave one alone so the app can grab it for itself.

Example 3.
With 258.XX drivers on Win7x64 you do not want to set SWAN_SYNC ... it will actually slow down.

<edit for clarification>
Don't use SWAN_SYNC on any 2XX (or earlier) cards

Overall WinXp runs much better than Vista/ Win7 and is on par with linux.
