Hi. I’ve got a program with kernel run times just short of a second, with the kernel being repeatedly called. If I run the code on my primary display device, Windows becomes a bit unresponsive, though there are no lock-ups during execution. Maximising and minimising of windows take a second or two, and sometimes the cursor stutters. It goes back to normal when the program exits.
However, If I run the same program on my secondary graphics card, which does not have any displays attached, there is no problems with windows response time.
My question is: has anyone else experienced this? Is this what one would expect? Are there any workarounds? I’d like to check before ordering a third graphic card to dedicate to display.
Thanks for reading.
