Optiscaler team fixes INT8 FSR 4 ghosting on RX 6000 series GPUs — adds support for the latest Adrenalin drivers

Optiscaler's team has addressed ghosting issues on RX 6000 series GPUs with the release of update 4.2.0b, which also adds support for the latest Adrenalin drivers. This update resolves ghosting problems associated with the unofficial INT8 build of FSR 4, enhancing the user experience. Optiscaler, a community-driven program, aims to provide gamers with upscaling options for supported games, leveraging leaked FSR 4 builds for improved image quality on older graphics cards. While AMD has not officially announced FSR 4 support for older GPUs, Optiscaler's efforts offer a workaround for users seeking enhanced visual fidelity on RDNA 2 and RDNA 3 GPUs.
