I've been able to tweak windows 10 to get two cases:
1. I found that at 0.5 timer resolution set, I get my DPC latency down to an average of 20μs with rare spikes while gaming to 500μs, with average sleep values of 1.5ms with a 0.5 delta.
2. I then tested many timer resolutions and found at 0.5120 timer resolution my sleep values dropped to 1ms with a very low delta (0.01), however my DPC latency went up to 500μs with rare spikes to 1000μs while gaming.
500μs = 0.5ms, so essentially 0.5ms has been deducted from the sleep, while 0.5ms is added to DPC latency.
So my question is, which case is theoretically better? 10-20μs DPC latency with 1.5ms sleep and 0.5 delta, or Higher 500μs DPC latency with 1ms sleep and 0.01 delta. Or are both literally identical in terms of the latency I will experience.
Cheers
