1、Previous generation World War ZWe used fixed-height dynamic resolution on consolesTAA as an antialiasing solution without upscaling on consolesFXAA for low-preset settings on PCRender resolutionTarget FPSXbox One/PS4960 x1080 1920 x108030Xbox One X2880 x2160 3840 x216030PS4 Pro1920 x1080 3200 x18003

2、0Much later we integrated FSR2 in the end of the frame,and it was a starting point of our AA/upscale journey on newer generation PlatformsWe use much more temporal techniques on different platforms now:FSR2FSR3FSR4XESS*DLSSMFSRTAA+FSR1PCAMD RDNA4NVIDIA 2000+seriesXBOX SERIES X/SPS5PS5 PROSteam DeckT

3、AA+FSR1 is intended as a cheap fallback solution.In practice,TAA is mostly used as an auxiliary temporal pass for several resources like circle of confusion,bloom mask,etc.*XeSS is only in RoadCraft for now Why we dont use FXAATAAResolution presetsConsolesXeSSRender resolutionTarget resolutionTarget
