OptiScaler Update for FSR 4: Unlocking Support Across Games
An update to OptiScaler now theoretically enables AMD's FSR 4 upscaling technology to function in numerous games, excluding those using Vulkan or anti-cheat systems. This update raises questions about why AMD hasn't expanded its own official support.
The latest iteration of FSR 4, AMD’s upscaling technology, is causing excitement despite its limited game compatibility. Recent updates to the OptiScaler tool allow it to support AMD’s FSR 4 in any game compatible with DLSS 2+ or FSR 2+, provided those games do not employ the Vulkan API or anti-cheat measures.
Despite this advance, using FSR 4 via OptiScaler isn’t straightforward; it requires users to navigate a more complex installation process. This may lead to some frustration among gamers who question why AMD itself doesn’t facilitate a more streamlined integration.
The question arises: why doesn’t AMD extend its official support to a broader selection of games, exploiting the potential of FSR 4’s technology? Despite posting a net profit of over $709 million with revenues of $7.4 billion in the first quarter of 2025, AMD’s handling of FSR 4’s game support seems less than optimal.
While projects like OptiScaler provide a workaround for users eager to leverage FSR 4’s benefits, many wonder about the disparity between what could be achieved and the current capabilities of AMD’s official offerings.
