We reported recently that Optiscaler, the community tool for enabling AMD’s latest FSR 4 upscaling technologies on older GPUs, had added support for Vulkan games. Now comes news that the tool enables FSR 4 on AMD RX 6000 GPUs, also known as RDNA 2 and now two generations old, without the need for driver mods.The situation prior to this latest update was that RDNA 2 GPUs, like the AMD Radeon RX 6800, could run a version of FSR 4 via Optiscaler, but that doing so required the use of modified versions of old GPU drivers. Part of the consequence of that was extensive image ghosting with FSR 4 enabled.As announced on Optiscaler’s Discord server (you can get an invite via the Gitbhub link posted above), this new update addresses those issues. “Fixes RDNA2 ghosting (or at least significantly improves it)”, the announcement says, adding, “works now on latest drivers” and “should remove the need for RDNA2 running old modified drivers on Windows.”The announcement of the latest release of Optiscaler also emphasises that, for now, there is no prospect of support for AMD’s very latest FSR 4.1 release on older RDNA 2 and RDNA 3 GPUs. “Please don’t ask about FSR 4.1, INT8 is never happening unless AMD does it,” the post says.Also, for clarity this update changes nothing for RDNA 3 GPUs. They already worked with more recent drivers and that hasn’t changed.Thanks to Optiscaler, owners of older RDNA 2 GPUs can get at least some of the benefits of…
