This is of course why I recommended turning HPET back on (otherwise Windows and programs have to fall back to less precise legacy timers).Lord of Pirates wrote:Have you tried checking your DPC latency? It might help to narrow down the cause of this.
However since this is AMD, maybe it's worth testing that out. But I think most any fairly recent platform (since the Core 2 Duo era) and OS should get better performance with this on.
Of course DPC latency will pick up other problems too, so that's a good recommendation.
