NVIDIA GeForce 536.67 WHQL Drivers Released
NVIDIA today released the GeForce 536.67 Game Ready drivers. The drivers introduce support for the GeForce RTX 4060 Ti 16 GB graphics card that's being launched today. The drivers also add optimization for "Portal: Prelude RTX" Among the couple of issues fixed with this release are a bug with GeForce Experience Freestyle filters that were causing games to crash; and increased DPC latency observed in Latencymon for RTX 30-series "Ampere" GPUs. Grab the drivers from the link below.

- Introduces support for the GeForce RTX 4060 Ti 16 GB.
- Portal: Prelude RTX
- Applying GeForce Experience Freestyle filters cause games to crash [4008945]
- Increase in DPC latency observed in Latencymon for Ampere-based GPUs [3952556]
- For notebook computers, issues can be system-specific and may not be seen on your particular notebook.
- [Halo Infinite] Significant performance drop is observed on Maxwell-based GPUs. [4052711]
- [Battlefield 2042] Game stability can decrease when applying GeForce Experience Freestyle filters. [4170804]
- This driver implements a fix for creative application stability issues seen during heavy memory usage. We've observed some situations where this fix has resulted in performance degradation when running Stable Diffusion and DaVinci Resolve. This will be addressed in an upcoming driver release.

Only on Ampere though..... would have guessed NVIDIA focus on fixing Ada first, I guess the root cause is different?
[I]NVIDIA Graphics Firmware Update Tool for DisplayPort 1.3 and 1.4 Displays[/I]
[I]Release Highlights[/I]
To enable the latest DisplayPort 1.3 / 1.4 features, your graphics card may require a firmware update.Without the update, systems that are connected to a DisplayPort 1.3 / 1.4 monitor could experience blank screens on boot until the OS loads, or could experience a hang on boot.
The NVIDIA Firmware Updater will detect whether the firmware update is needed, and if needed, will give the user the option to update it.
If you are currently experiencing a blank screen or hang on boot with a DP 1.3 or 1.4 monitor, please try one of the following workarounds in order to run the tool:
- Boot using DVI or HDMI
- Boot using a different monitor
- Change boot mode from UEFI to Legacy; or Legacy to UEFI.
- Boot using an alternate graphics source (secondary or integrated graphics card)
Once you have the tool downloaded, please run the tool and follow the on-screen instructions.[I]Supported Products[/I]

RTX A2000 6 GB
BTW This is after setting manually the affinity to a less used cpu. By default it would load cpu 0 to the extend the bar in latencymon would be even red.
The only problem I had was with adaptive/optimal power management. Every time the power mode changed, the latency was spiking to 2000-3000 us. Those power management options were causing huge stutters in games with low GPU load, and even during video playback when the memory clock kept changing constantly between 405 and 810 MHz (P8 and P5 modes).
On my 4070, the latency is usually below 300 us, most of the time below 200. But I have Prefer max performance forced constantly, even for internet browsing.
The Network Driver Interface Specification spikes to ~800 sometimes. I don't think it causes anything bad, though.
The higher DPC latency? It's an intel problem and windows 11 is putting in the work to minimise it (possibly at the expensive of other CPU designs, in outlier cases)
Windows 11 vs 10: Intel CPUs apparently sluggish, and it's worse without Microsoft's help - Neowin
11/12/13 gen suffer the issue since the 'thread director' was adjusted in the CPUs, apparently
inter-core latency is believed to be the issue
Cause the 13th gen... doesnt do so well. Data within the one core is faster, as you'd expect with the newer gen CPU - but all core to core latency is worse at every step, averaging about 50% worse
for A2000 (Ampere-based GPU) it changes from 15watt to 30watt. (2 monitors connected to GPU)
It's the only way to get perfect stutter-free video playback. The power increase is irrelevant to me. I only care about power during gaming because of heat output.
my 3090 is 12W idle and my entire PC with a 32" monitor doesn't use that for 4K playback
Looks good here on AMD/3090
seems i can be smug that i'm faster than 10th and 13th gen intel in DPC latency
RTX 2080 Ti. Latest WHQL drivers. No manual affinity.
Set "Prefer max performance" power management in the NV Control Panel, restart and check the latency then. I'm almost sure you'll get nowhere near 1000 us. Or check a game with Prefer max performance, so that the power state is always P0.
I will try a game with latencymon running in the background...
The key is that intel 12/13th gen have 50%+ latency between cores, even if its just within the single set of 8 P-cores, and it's showing up in places like Nvidias drivers, that apparently relied on the low latency
Educated guess that it's now relying on a software scheduler and not a hardware one (that parts not a guess), so theres a time penalty where it has to process where to move threads over to - so you get good performance in multi threaded tasks, but theres a % chance of a slowdown/stutter if things go to sub-optimal places and need to get moved around. you don't have system specs, but if you wanna post a zentimings screenshot i've got a theory about what might be going on there
mostly because of this comment You arent on the windows power saving plan are you? Latest BIOS?
Im on the hidden Ultimate Performance plan. BIOS is pretty much the latest. There is F37e released just a few days ago but it's based on the same AGESA version as F37b.
You're breaking the cores being able to sleep, which harms their boost performance.
You should avoid things like that in the future, as they break a lot more than they fix - they often come paired with lots of other tweaks that only help reduce the damage tweaks like that power plan cause in the first place.
As someone running even higher IF speeds than you, it does sound like the traditional infinity fabric dropout - which component drops depends on the board and CPU, but it can be CPU, PCI-E lanes, USB or SATA.
Your VDIMM is really high, which adds the risk of simple RAM instability being the cause too. B-die doesnt like heat at all, and can get unstable as low as 40c with such high voltages - it only takes a few correctable errors to make a stutter, or the high power draw to cause an IF dropout
I'm pretty sure you need to raise other voltages at the same time as VDIMM, but 1.60v is so high i'm not sure it's even safe to do so.
first google result for B-die on AM4 confirmed thatidea
There are also people with similar RAM that's hynix, which behaves entirely differently
Bought Viper Steel 4400MHz c19 and turns out to be HYNIX die. Have anyone experienced the same thing? : overclocking (reddit.com) Your problems not GPU driver related, it's that you're running some extremely uncommon and not recommended tweaks in hardware and software.
The idle power consumption is up 4watt. From ~15watt to ~19watt.
I have the power saving options turned on.
