hi!

My system:
phenom 9950be
nforce 750a chipset (gf 8300 gpu)
geforce 9800gtx
geforce 8600gt
One display per card.
vista64 sp1

I used the folding@home gpu client with configuration for all three cards, but I want to consolidate to boinc, which I already used for 4 cpu-threads.

with driver 180.x only one gpu was used by boinc 6.6.20.
now updated to driver 185.xx and boinc 6.6.31.
added a new file 'cc_config.xml' to boinc folder to set the ...<use_all_gpus>1... option.
now the 9800gtx and 8600gt gpus are used, but not the 8300 integrated in nforce 750a.
How can it be employed?

To watch video (with overlay) I allways have to stop the gpu-task corresponding to the video-display. otherwise the video achieves just about 2fps.

Is there a way automatically stopping the gpu-processing when an overlay-video is detected?

greetings

Hi, just for the sake of fun and testing: what video player are you using? If VLC or an mplayer-derivative, you could try to change the output driver to "opengl".

@TG: thank you for your answer.

I typically use the mediaplayer classic, vlc, powerdvd, smplayer and the pinnacle TV application TVCenterPro for dvb-t.
The OpenGL option (and others) in vlc and smplayer did not change for the better.
It seems that video-overlays suffer badly from gpugrid.

Also normal applications refresh noticeable slower. Writing this text in Firefox I notice a distracting lag of about .3 of a second before the caracters appear or got deleted. Same with dragging windows or work with graphic applications.
I expect this slowdown is usual with gpgpu, but would like to reduce it a little.
- and automatically suspend gpugrid for videos.

greetings
