Add FSR4 to DCS ( current methods are severely insufficient for AMD users )

[jf17enjoyer12]

With the new series of AMD GPU's which exploded in popularity AMD users have been in desperate need of FSR4 because the current options are between TAA which makes everything blurry and MSAA which has a massive performance hit and is very inefective. Giving us FSR4 would allow AMD users to have an equivalent of DLSS4 and an actually viable antyaliasing/upscaling technique. It would help greatly and i assume it would be relatively easy to implement since we already have a version of FSR in game however it is unusable because of how ancient it is.
