AMD Radeon RX 7800 XT Performance Reportedly Up To 10% Worse On FSR 4.1 Than FSR 3.1
Back in June, AMD released Fidelity Super Resolution 4.1 (FSR 4.1) support for its older Radeon RX 7000 series GPUs, thus enticing Radeon GPU gamers with the promise of smoother performance. However, that may not necessarily be the case, based on the findings of German tech outlet ComputerBase. ComputerBase tested FSR 4.1 with two GPUs: […] The post AMD Radeon RX 7800 XT Performance Reportedly Up…
In a recent report by German tech outlet ComputerBase, it has been found that the AMD Radeon RX 7800 XT experiences a performance loss of up to 10% when using the new FSR 4.1 technology compared to the FSR 3.1 version. The test was carried out on the RX 7800 XT and RX 7600 GPUs, with resolutions ranging from 2560 x 1440 to 3440 x 1440.
The findings indicate that the 7800 XT's performance drops from 70 fps on FSR 3.1 to 66.1 fps when using FSR 4.1, representing a 7% decrease. Similarly, the RX 7600's performance drops from 36.5 fps to 33.1 fps when moving from FSR 3.1 to FSR 4.1. The gap widens further at higher resolutions, with the 7800 XT experiencing an 8% drop from 59.4 fps to 54.8 fps and from 43.4 fps to 39.2 fps at 4K.
It is worth noting that the performance penalties vary depending on the game, ranging from 2% to 18%. FSR 4.1 running in Performance mode is reported to produce better visuals, but it comes at the cost of reduced performance compared to FSR 3.1 Quality Mode.
