Does DLSS work for anyone?


I''ve been testing the new update since a few hours, and it's really been a huge change from the previous major version. Vulkan support is a killer feature.

However, when cross-referencing with the Windows build, I've noticed that DLSS isn't supported on Linux (yet?) - on Windows I am able to choose an option for DLSS from "Performance" to "Quality".

 

Since I am running somewhat of an odd resolution at 3400x1440, I've been wondering if, on Linux, there may be some DLSS configuration options for, say, 1920x1080 or similarly more conventional resolutions.

Or might I be missing some module to enable support? I am running a fairly standard setup using proprietary driver version 455.38, which should - in theory - have DLSS 2.0 support.

If anyone has some info to share on this I'd much appreciate it! :)

 

Also, should enabling DLSS support for Linux be passed as a suggestion to the devs? Since newer Nvidia drivers support it even on Linux, I feel this might be worth a shot.

No it is turned off, but that is no surprise to me.  I thought it was something they made special for Microsoft anyway.  Where they sample 8k res at Nvidia's central computer and send them to us for improved graphics since I am at 4k.   The box is there i just can not select it.

Hello @Xakep_SDK,

 

I know the Linux Nvidia driver supports DLSS but do you know of where it actually states the Linux driver has DLSS 2.0 support? I've had a quite look myself but cannot find anywhere where it states it. I can report this if someone can point me to where it's stated DLSS 2.0 is support in the Linux driver.

It's supported since 450.57

@Xakep_SDK,

 

Yes, However is there anywhere where it states the Linux driver supports DLSS 2.0 specifically? You would assume it would support DLSS 2.0 as it's all DLSS but to would be nice to solid evidence for it.

DLSS is NVIDIA RTX-2000 / 3000 exclusive, u cant use it without a RTX-Card, but it should work since the Patch is out

I have asked nvidia developer

The driver supports DLSS and NGX Features via the NGX component starting with release series 450. However DLSS and NGX Feature support may differ between versions as these aren’t driver components, so it’s best to check in support audiences for those specific components.

 

With that in mind having worked on the implementation I know that:
DLSS has support for Linux with DLSS 2.0 and above. DLSS versions prior to 2.0 are not supported on Linux.

@Xakep_SDK,

 

Thank you, That answers that one then, Do you have a 20 series or newer card? If so could you please post your full system information, A screenshot of the DLSS option in game with the mouse over popup showing and a .clog file from that session so I can forward this?
