Redditor’s guide shows how to enable XeSS 3 Multi Frame Gen on Intel Arc B580 and Alchemist GPUs
Turns out, enabling XeSS3 is as easy as swapping a few files.
I’m not sure why Intel decided to launch XeSS3 exclusively with Panther Lake laptops. Sure, it’s great that they support it, but the vast majority of Intel graphics users would rather see this support reaching older architecture. Something that Intel promised to fulfill, but this month.
Some gamers aren’t that patient, so they decided to act on their own. Right now, XeSS 3 multi-frame generation is now live on systems with Intel’s Xe3 graphics, such as Panther Lake iGPUs, where the feature is exposed through Intel’s control panel. The “XeSS Override” toggle is temporarily limited to Xe3, which is why Arc owners keep running into mixed messaging about support.
In the IntelArc Reddit, users onehoon and Aggressive-Camel8166 described a workaround that uses files already bundled inside the latest driver package. The short version is: extract the driver, copy two XeSS-related DLLs from one folder to another (listed as “8362” and “8452” in the post), then reinstall from the extracted folder after a clean driver removal. The same thread also mentions an extra step some users take per game, by renaming the DLLs and dropping them into the game directory.
How to enable XeSS3 on Battlemage/Alchemist GPUs
- Download the latest Intel graphics driver package.
- Extract the driver package with 7-Zip to a folder.
- Open the
8362folder.- Find
igxell.dllandigxess_fg.dll.- Copy both DLLs into the
8452folder and overwrite when prompted.- Use DDU to remove the current graphics driver and Intel Graphics Software (IGS).
- Install the driver from the extracted folder, and ignore the warning during installation.
- Optional per-game step mentioned in the thread:
- Rename the DLLs from
ig*tolib*(example:igxell.dll→libxell.dll,igxess_fg.dll→libxess_fg.dll).- Place the renamed DLLs into the game’s folder, replacing the existing files if needed.
One should be aware that XeSS3 is not a new AI upscaling model, in fact, it uses the same upscaling algoritms at XeSS2, so if you are after higher quality of performance here, this is not a mod for you. However, XeSS 3 also brings XeSS Multi-Frame-Generation. Users in the thread posted early results in Cyberpunk 2077, including a warning that 4x modes can hit the XMX hardware hard, and that performance can drop while recording.
Official support is coming this month , it should cover Alchemist and Battlemage GPUs. Users on Reddit have already shown it works on Claw gaming handheld, even on the first gen with Meteor Lake.
