Hoirtel Posted July 16, 2020 Posted July 16, 2020 Does anyone know a bit more detail about this patch note: DCS affinity to zero CPU core fixed. Interested to know what the problem was and what this is doing to fix or enhance the DCS experience. Apologies if I have missed a thread on this elsewhere, I couldn't find it.
Ramsay Posted July 16, 2020 Posted July 16, 2020 Interested to know what the problem was and what this is doing to fix or enhance the DCS experience. Apologies if I have missed a thread on this elsewhere, I couldn't find it. The forum search function helps with questions like yours. Sound crackling Update: The problem is in the CPU cores allocation. The sound engine just does not have enough CPU time to do its job because of other (unrelated) tasks being assigned to the same CPU core. Should be fixed in the next openbeta. CPU use First core getting stuck at 100% usage, even in the main menu. The problem goes away if I disable and re-enable that core in task manager. I am not sure when exactly problem appeared. Maybe after new DCS version or maybe after windows 2004 update. Anyone else experiencing the same issue?

Hoirtel Posted July 16, 2020 Author Posted July 16, 2020 Thanks you. I did use the search but wasn't sure if what I found was related to this problem/fix as there are lots of threads and posts about CPU use generally - searching is only as good as the keywords used

Mustang Posted July 16, 2020 Posted July 16, 2020 As a side note the affinity_mask parameter in autoexec.cfg still doesn't work properly, it was slated to be fixed for this beta https://forums.eagle.ru/showthread.php?t=264593&page=2 you can still force desired core allocation via task manager but it's a bit awkward, would much prefer the autoexec.cfg method working.
