Sorry, a few rookie-questions:

1. What do you use for measuring latency in W10 anno 2018 ?
2. Is free version of LatencyMon 6.7 ok for normal DIY pc-builders ? (full version is terrible expensive)
3. Just threw a Nvidia P400 into my new build, as my old GTX950 did suck in 4K,.. is P400 decent ?

Thanks in advance :)

1. LatencyMon
2. "LatencyMon Professional offers the same great features as LatencyMon Home Edition but comes with a license that allows you to use the software in any commercial environment."
3. Could you test the DPC latency and post it here?

Thanks,
Lesha
It's easy if you know how

Thanks Lesha

Good to know the free version is sufficient, becourse for long time there was no latency-toll for W10 as far as I could tell

I will try to post back later, but it will take several weaks, my system is being rebuild in a new case, with water-cooling and more fans etc.

As the driver is different the Quadro P400 probably will have better latency, but it is a slower card.

I built a new Ryzen 3700x system reusing only my 1050ti GPU and latency persisted, so I figured the Nvidia card was the culprit. However, latest MS Windows Insider's build plus AMD Master Utility (default Creator's setting) resolved latency issues for me. Extremely impressed with Ryzen 7 3700x. Cool, fast & quiet!

Jfyi in Windows 10 v1903 was a dpc latency issue which was just recently resolved in July 2019 Update rollup.

Did anyone ever try Nvidia's "Studio Driver"? This is a special driver, optimized for graphics professionals. I've tried to find DPC latency figures for that driver but I can't find anything. Would anyone with an nVidia card be so kind as to try it out? (Given the name, I figure it should be good for us musicians... :D)

No difference to DPC, I tried it a few weeks back. It's optimization for rendering and video platforms which is offline (none realtime) work in general. It's the sort of workload that absolutely doesn't care about DPC in the slightest, so they've not really considered it when rolling out these new ones I suspect.

Honestly, I think they've finally just given up trying to convince the average Premier user that Quadro has a point.

To uninstall the current driver always use DDU and
set it to reboot in safe mode to remove the driver.

Type the following commands to disable HPET

Restart the PC for the changes to take place.

Use 1usmus Custom Power Plan 1.1 for Ryzen 3000 and set the Win Power Plan to

In the motherboard BIOS:
- Spread Spectrum Control = Disabled
- PCIe = GEN3 (less bugs and more silent chipset fan)
- Global C-state Control = Enabled
- Power Supply Idle Control = Low Current Idle
- CPPC = Enabled
- CPPC Preferred Cores = Enabled
- AMD Cool'n'Quiet = Enabled
- PPC Adjustment = PState 0
- PBO = Disabled (initially I keep it disabled)
https://www.reddit.com/r/Amd/comments/d ... uggestion/

Now play with the machine and if all is OK can set the CPU CLOCK RATIO
to a fixed value to keep it locked at higher speed, lest say the
BLK = 100MHz with CPU CLOCK RATIO = 42 will get 4200MHz in all CPU cores.
Attention, max temperature for the CPU is 75° Celsius or 167 °Fahrenheit, NOT MORE! :-o

Hi, i just wanted to add this..:

fresh..
AMD 3900x Ryzon CPU
Nvidia GTX 1660 Ti (Gigabyte) Graphics
ASUS Rog Stryx mainboard B450-F
64gB Crucial 3200 ram

Mentioned above and very good: AMD Ryzen Master Software set to "Creator" profile.
+Ryzen high performance energy-profile.

I can match or beat any latency numbers mentioned here in this thread..

---
Also i installed only the "Studio" graphics driver (no physX etc.)and put the 3D mode on high performance, BUT the low LatencyMon numbers were already there before + i use GeForce Experience.
I'm just looking to "max out" stability...and it looks good....So far.

As written above: Cool, fast 'n quiet..

(default Bios with only the Ram profile set for factory timings / Windows 10 64Bit with communication or reports mostly turned off)

So, I just upgraded my Sapphire Nitro+ Radeon RX 590 to a Gigabyte GeForce RTX 2060 Super Gaming OC 3X 8G. Fearing the dreaded increase of DPC latency, I ran two long sessions of Latencymon. Here are the results:

Gigabyte GeForce RTX 2060 Super Gaming OC 3X 8G

As you can see, the NVidia result is quite acceptable, even with GeForce experience installed!
