For completeness, I might maybe should have added that I'm using the stock 1.02 from the project, no app_info file.

the app_info.xml file really isn't necessary unless you either want to change the number of simultaneously running MW@H tasks to something greater than 1 or improve GUI lag/set process priority/etc. via command line parameters.

This is exactly what to expect if you are using 7.x.x with 'old style' cache settings - something like CE=0 and ED=3.0 for example.

Thought 11.9 should be working for XP 32bit with HD5850?

Still can't get any WUs for my XP 32 bit box if I use the app_info I was using before to reduce the GPU usage. Worked fine before. Anyone have a suggestion. File used is below.
<app_info>

<app><!-- GPU app v0.82 for MW Separation -->
<name>milkyway</name>
</app>
<file_info>
<name>milkyway_separation_0.82_windows_intelx86__ati14.exe</name>
<executable/>
</file_info>

<app_version>
<app_name>milkyway</app_name>
<version_num>82</version_num>
<plan_class>ati14</plan_class>
<flops>1.0e11</flops>
<avg_ncpus>0.05</avg_ncpus>
<max_ncpus>1</max_ncpus>
<coproc>
<type>ATI</type>
<count>1.0</count>
</coproc>
<cmdline>--gpu-target-frequency 80 --gpu-polling-mode 16 --process-priority 1</cmdline>
<file_ref>
<file_name>milkyway_separation_0.82_windows_intelx86__ati14.exe</file_name>
<main_program/>
</file_ref>
</app_version>

</app_info>

Took the side off the case so..

Cant help with the detail of the settings as I dont use the cmd line arguements, but whilst waiting for someone who does .... its going to help them if you describe a little more what you mean by bogging down.

eg mouse gittery, screen slow to redraw, scrolling inside individual windows juddery, juddery when moving a window, screen blemishes, active BOINC window not refreshing the counters.... others ...

all the above rofl :)

If you use GPU-Z I bet it shows your GPU being used at 98+%. No wonder your switch between programmes and other applications is slow. You need an app_info.xml file to bring the GPU usage down to 90% to 95%.

That is what I did on my XP 32 bit box.

Could you be a bit more specific about "bogs down?" Just graphics lag? It shouldn't be different. I don't see any real difference between the timings of the GPU results from either of your system which is what I would assume your problem is
