F@H problem on Win7

[Assimilator1]

It's been a few months since I last tried it, but when in Win7 with F@H running & then playing Rome Total War I a get perodic jerking & stuttering of the game. Stopping F@H cures it but then I have 2-3 cores sitting idle, plus I have to remember to switch it back on! :$

I lowered F@Hs priority from normal to low, no change.
Anyone got any ideas on how to fix this?

I'm currently back to using XP on my HDD instead of Win7 of my SSD (partly because of this problem & other non DC issues), frustrating not to use my nice new & fast SSD!

open up notepad and save this *.* not .txt as app_config.xml under your directory path which is hidden called "ProgramData\BOINC\projects\foldingathome-or-whatever-name\
max_concurrent is the number of cpu to be used and try this approach of using 2 or 3 cpu's

<app_config>
<app>
<name>short-name-of-program-here</name>
<max_concurrent>2</max_concurrent>
</app>
</app_config>

StitchExperiment: F@H (folding@home) is not an BOINC-app, it is its own DC-program, with different settings and different way of setting up ...

I think that's just the way F@H is. It's quite a pig, for an app that is supposed to use "idle cycles". Try using the SMP flag, and set the number of cores less than you have, to leave some CPU cores left for other things?

I'm guessing it is the GPU app that is causing the problem.

I think you are stuck pausing to game and then restarting Folding.

Thx for the replies guys .

Not using GPU for F@H, it's no longer supported (see sig for rig specs, Q6600).
I realised I was using an old version of F@H (v7.2 or 7.1.x, can't remember exactly offhand), so I've now installed the latest version 7.3.6 & it has a power slider bar, which allows me to do what Virtual Larry said via GUI .
I'm going to try it at full power 1st to see if the new version still lags the game with all cores being used.

[update]
Well I thought the new version had fixed it even when at full power, & for the 1st ~5mins of playing RTW it was fine, then the stuttering started again . So I'm going to try the medium setting (4 cores @75%) now & see if that fares better.

Btw just to re-iterate, this problem does not occur under Win XP.

[update2]
Yep, setting it to medium fixed it, but it still means I have to remember to change it each time I start/stop the game.
Wierd that it only does it on Win 7, any ideas why &/or how to fix it?
