The game needs better antialiasing techniques. MSAA is somewhat dated and doesn’t cover alpha textures, which makes it absolutely terrible for this game with its huge amounts of greenery. Downsampling is nice, but current GPU requirements are too steep. I cannot run the game at stable 60fps in 4K on 3070Ti.
Alternative and much better solution would be either implementing DLAA or DLSS / FSR. Setting the game to 4K using DSR and then applying DLSS / FSR will probably yield to much better results than native 4K in terms of fps with similar visual quality.
