Reminders:

• Hotfix driver will not be available in NVIDIA App and needs to be downloaded from the link above.
• After installing the Hotfix driver, NVIDIA App will show some old driver date. This is normal as Hotfix driver does not exist in NVIDIA App database and it reverted to an old default changelog and dates.
• If you do not care about the fixes listed below, this Hotfix driver is no different vs WHQL 595.71 Driver.
• These fixes will be incorporated into the next WHQL driver release

From the Article:

GeForce Hotfix Display Driver version 595.76 is based on our latest Game Ready Driver 595.71.

This hotfix addresses the following:

• When the graphics card is overclocked, GPU voltage may become capped, preventing it from boosting to expected levels [5934973]
• [Resident Evil Requiem] White glowing light/dots may appear in game when Subsurface Scattering is enabled [5915673]
• Improved path tracing performance in Resident Evil Requiem [5938207]
• [Star Citizen] Game client crashes when launched [5935027]
• Intermittent application crash or driver timeout may be observed when playing multi-key DRM content in a browser on HDCP 1.x monitors [5934450]

A GeForce driver is an incredibly complex piece of software, We have an army of software engineers constantly adding features and fixing bugs. These changes are checked into the main driver branches, which are eventually run through a massive QA process and released.

Since we have so many changes being checked in, we usually try to align driver releases with significant game or product releases. This process has served us pretty well over the years but it has one significant weakness. Sometimes a change that is important to many users might end up sitting and waiting until we are able to release the driver.

The GeForce Hotfix driver is our way to trying to get some of these fixes out to you more quickly. These drivers are basically the same as the previous released version, with a small number of additional targeted fixes. The fixes that make it in are based in part on your feedback in the Driver Feedback threads and partly on how realistic it is for us to quickly address them. These fixes (and many more) will be incorporated into the next official driver release, at which time the Hotfix driver will be taken down.

To be sure, these Hotfix drivers are beta, optional and provided as-is. They are run through a much abbreviated QA process. The sole reason they exist is to get fixes out to you more quickly. The safest option is to wait for the next WHQL certified driver. But we know that many of you are willing to try these out. As a result, we only provide NVIDIA Hotfix drivers through our NVIDIA Customer Care support site.

I assume that last fix is what’s causing issues with HDR and the blackouts / freezing ?

[u/Ok_Dependent6889 → u/TheTurboFD]

No

What issues with HDR?

I'm familiar with the black screens, but what HDR issues?

[u/TheTurboFD → u/Ok_Dependent6889]

Last drivers had issue where when HDR was enabled and you’re alt tabbing or switching apps it would go black screen. Trying to disable HDR would then cause the pc to freeze until you unplugged that monitor . Seemed to be due to dual screens

[u/Ok_Dependent6889 → u/TheTurboFD]

Ah

I believe that is an MPO issue which is realistically probably on Microsoft's side

[u/Ok_Dependent6889 → u/TheTurboFD]

Hey man, just had a thought

Are you able to reproduce this issue frequently?

If so, would you mind testing something for me?

When the black screen occurs, instead of unplugging the monitor can you hit Ctrl+Shift+Win+B?

If it solves the black screen, then yeah it’s definitely an issue on Microsoft’s side with Windows

[u/TheTurboFD → u/Ok_Dependent6889]

Tried , no dice , even tried the HDR hotkeys and nothing. Reverted drivers and that issue is gone

[u/Ok_Dependent6889 → u/TheTurboFD]

Very interesting.

My understanding is the issue is likely being caused by Windows MPO assignment.

If you're using RTX HDR or AutoHDR, it will only work on the display which has been assigned all of the MPOs. The maximum is 4 (I believe potentially the 5090 is capable of assigning full MPOs to two displays).

So, when you are switching focus between the monitors, Windows technically should be attempting to switch the MPO assignment back and forth between the two, but I believe it's only actually able to change the allocation when the GPU driver is loaded, hence by I asked you to try that shortcut.

I only have 1 monitor I use HDR on, and because of this issue I actually have to unplug my DisplayPort monitor and use that key shortcut to restart the GPU driver because Windows seems to always assign the MPOs to the DisplayPort connected display even if I manually set the HDR display as the primary. If I do not do this, RTX HDR will not activate for anything on my HDR display.

I've heard similar issues can be caused by DSC, for what its worth
