Microsoft compared FSR 4 on Xbox with PlayStation scaling technologies

Microsoft has shared official technical data on AMD FSR4 scaling performance on Xbox consoles. On Microsoft gaming systems, the technology will feature two performance profiles: FULL FSR4, with image quality similar to the PC version, and LITE FSR4, with reduced quality similar to PlayStation QSSR. Scaling time depends on the target resolution and the number of calculations performed at different precisions. RDNA graphics units with a 32-bit architecture can simultaneously process one FP32, two FP16, four INT8 or FP8, or eight INT4 operations.

The time spent on scaling is subtracted from the overall frame budget, which is 16.7 ms for a target 60 fps and 33.3 ms for 30 fps. According to…
