I can confirm that one or more of the gpu projects slows my whole computer down

The default setting for use of the GPU is only when the computer is not in use by a person (idle). This was done with the thought in mind that the GPU will slow down a system when calculations are done on that GPU.


Especially when you're gaming, the game and the calculations will both fight for the same hardware to use, which will slow both down. So either set BOINC back on only use GPU when computer is idle, or use the exclusive applications options (<exclusive_app> and <exclusive_gpu_app>) in a cc_config.xml file to stop BOINC from allowing calculations to be done when it detects that a certain application is in memory.

e.g.

<cc_config>
<log_flags>
</log_flags>
<options>
<exclusive_app>Notepad.exe</exclusive_app>
<exclusive_app>winamp.exe</exclusive_app>
<exclusive_gpu_app>GTAV.exe</exclusive_gpu_app>
<exclusive_gpu_app>NFS.exe<exclusive_gpu_app>
</options>
</cc_config>

Multiple applications can be excluded, each on their own line.
Full path to where the application lives isn't needed.
The <exclusive_app> option will suspend the whole of BOINC (CPU and GPU).
The <exclusive_gpu_app> option will only suspend the GPU, but allow CPU tasks to continue.
