HelixSR 2.0 cuts DLSS frame generation GPU overhead by 20% on AMD hardware

HelixSR 2.0 brings Nvidia DLSS to AMD hardware like the Steam Deck, cutting frame generation GPU overhead by 20% at 1080p and 1440p.

GAME PERFORMANCE

HelixSR 2.0 is out for download on GitHub and it now supports upscaling with , as well as on devices (like the ). This is important because it adds another performance option for portable hardware owners, who were previously unable to take advantage of Nvidia's proprietary tech. Now people will be able to get better frame rates and image quality from the upscaling on compatible AMD GPUs (without having to wait for proper driver support).

New Light Mode reduces GPU time for frame generation on Steam Deck

This software update is specifically designed around the limitations of portable devices by finding better ways to integrate frame generation. HelixSR allows users to get Nvidia DLSS upscaling tech working on AMD devices (like the Deck that's very popular). This opens the door for anyone to overcome the hardware limitations which would normally prevent DLSS from working on anything besides Nvidia graphics cards.

  • HelixSR Version: 2.0.0
  • GPU Time Reduction (1080p/1440p): 20%
  • GPU Time Reduction (4K): 11%
  • Supported APIs: DirectX 11, Vulkan

Developer says the new default Light Mode saves about 20% of GPU time for generating frames (at 1080p and 1440p). At 4K they're saying it saves roughly 11% over past versions. Support for DX11 and Vulkan games has been added, which means more games can benefit from the upscaling features.

There are big focuses on optimized memory and better high-res upscaling speed with this update. However, they mention there could be some duplication issues when you're moving things around in the HUD in generated frames. This could potentially impact your experience in some games. Keep in mind frame generation can add input latency when base frame rates are low, so expect some lag in action-packed situations.

Many of the same balance and stability issues were raised when we went over the last HelixSR update. We're now seeing further progression of that work to get DLSS working on non-Nvidia hardware, with some of the performance overheads cleaned up. It's still a free download that will need manual configuration if you want to use it.
