Open source Linux tool brings Reflex style low latency gaming to AMD and Intel GPUs

Linux gaming may soon get a major latency boost thanks to a new open source project called low_latency_layer. The tool acts as a compatibility layer that brings NVIDIA Reflex and AMD Anti Lag 2 style behavior to Linux, including support for AMD and Intel GPUs in games that normally only expose NVIDIA Reflex.

The project was created by Korthos Software to solve a long running Linux gaming problem. On Windows, NVIDIA Reflex and AMD Anti Lag 2 can reduce input latency by better coordinating game simulation and rendered frames. On Linux, these features have not been widely supported because the required driver level support has been missing.

The new shim works around that limitation. Instead of waiting for every GPU vendor and game developer to support these systems natively on Linux, low_latency_layer gives players a way to use similar latency reduction methods across different hardware.

The early results are promising. In the developer’s own testing, Marvel Rivals input latency on a Radeon RX 7900 XTX dropped from around 40ms to as low as 20ms when using Reflex through the shim. That is a large improvement, especially for fast competitive games where input response matters.

The developer tested the tool across six games: The Finals, Counter Strike 2, Cyberpunk 2077, Resident Evil: Requiem, Marvel Rivals, and Overwatch 2. The testing reportedly involved hundreds of runs per game, using a 540Hz monitor with NVIDIA Reflex Analyzer to measure end to end input latency.

In those tests, the Linux shim delivered results that were equal to or better than proprietary Reflex and Anti Lag 2 behavior on Windows. That does not mean every game or system will see the same gains, but it shows that Linux gaming latency can be improved without waiting for one vendor’s closed solution.

The vendor neutral approach is the most interesting part. If a game supports Reflex, AMD and Intel GPU owners on Linux may still benefit through the shim. That could make low latency features more widely available, especially on Linux systems where official support is often limited.

There are still barriers. The tool is not packaged for easy installation yet. Players need to compile it themselves and install dependencies such as cmake, Vulkan headers, and Vulkan utility libraries. Proton games may also need extra tweaking.

That means this is not ready for casual Linux players yet. But it could become important if Valve or another major Linux gaming platform decides to integrate similar technology into SteamOS.

For Steam Deck, future Steam Machines, and Linux desktop gamers, this kind of project matters. Linux gaming has already improved a lot through Proton, Mesa, and SteamOS, but input latency is still one area where Windows has often had better vendor support.

low_latency_layer shows that the gap can shrink. If the project matures and becomes easier to use, Linux players could get Reflex style responsiveness across more GPUs and more games without being locked into one brand.
