Support for AMD FSR (FidelityFX Super Resolution) is now available directly in Epic’s Unreal Engine thanks to a newly released plugin. Do note that Unreal Engine 4 version 4.27.1 is required to use it.
After the fairly simple installation, game developers will have the following options at their disposal:
FSR 1.0 can be enabled or disabled with the CVar
r.FidelityFX.FSR.Enabled.Upscaling percentage can be tuned with the CVarr.ScreenPercentage. We recommend the following values:
- Ultra Quality :
r.ScreenPercentage 77
Produces an image with quality virtually indistinguishable from native rendering. It should be selected when the highest quality is desired.- Quality :
r.ScreenPercentage 67
Produces a super resolution image with quality representative of native rendering, with a sizeable performance gain.- Balanced :
r.ScreenPercentage 59
Produces a super resolution image approximating native rendering quality, with a major performance gain compared to native.- Performance :
r.ScreenPercentage 50
Visibly impacts image quality and should only be selected in situations where needing additional performance is critical.The UE4 FSR 1.0 plugin requires ensuring that
r.ScreenPercentagemeets or exceeds a minimum value of 50 at all times.
Needless to say, this will allow the many Unreal Engine developers to implement FidelityFX Super Resolution more easily into their games, even though it was already far from problematic. There’s already a large list of titles supporting FSR, and it’s destined to grow in the future with the likes of Amid Evil, Asterigos, Century: Age of Ashes, Edge of the Abyss: Awaken, Farming Simulator 22, Forspoken, Ghostrunner, God of War, Hellish Quart, Hot Wheels Unleashed, Iron Conflict, KEO, LEGO Builder’s Journey, Myth of Empires, No Man’s Sky, Raji: An Ancient Epic, Second Extinction, Swordsman Remake, The Elder Scrolls Online, Warface, Warhammer Vermintide II, Workshop Simulator, and X4: Foundations.
