doesn't seem to mention it anywhere,did you try various nv drivers or just one ?
I just checked the latest,
446.14 is one messy driver when it comes to latency.I'm not having any frametime/stutter issues on it though and gameplay is smooth as ever.
I think your dpc issues are not related to stutter in games,they shouldn't be.they're a separate issue on your machine.when the card goes into full power mode dpc latency tends to stay normal.it's a problem on light loads e.g. you can get crackling audio when watching youtube etc.
I tested
445.98 and
445.87,solid,not the best I've seen but there's nothing very alarming going on.
.87 seems a little bit more consistent in-game latency, .98 seems a little bit better in idle/light gpu load,but like I said - even with 446.14 which obviously struggles with latency on desktop,there's no difference between those three drivers in games.all three produce a perfectly smooth frametime record.
like I said,your latency problems are
a separate issue and they are
nv driver related.
your stuttering/frametime problems - that's sth else
