We have an update on AMD’s FidelityFX Super Resolution 3 which reveals a crucial aspect of how it will work compared to the previous FSR versions.
Even though we already know from the latest GDC event that FSR 3 will bring frame interpolation, we didn’t know how much frame generation AMD is trying to create here.
But in the new leak which was reported by Twitter user Kepler, he pointed out that the latest GPU open driver document from AMD is containing two lines of code that explicitly state the Frame Generation intensity. According to the user, the FrameGenRatio here is 4 which implies that FSR 3 is going to create up to 4 interpolated frames for every real frame in games.
This is very much different from Nvidia’s DLSS 3 frame generation which can only produce one interpolation frame AKA fake frame for each real frame in games. Through Frame generation and Upscaling combined, Nvidia is able to reach 2-3 times higher fps than without frame generation.
Looks like AMD is trying to quadruple that number by adding 4 fake frames in between each frame so that the users who are getting for example 30 fps can achieve fps numbers as high as 90. Kepler further adds that FSR3 is going to be a driver-side feature and that means unlike FSR 1 and 2, FSR 3 won’t be working on Nvidia GPUs.
Well, that doesn’t bother me much but what bothers me is how the frame interpolation in FSR 3 will affect the gameplay. Nvidia’s own DLSS 3 frame generation is known for producing ghosting and artifacts and that’s by just 1 additional fake frame between two real frames.
I wonder how adding frames four times more than the real ones will affect ghosting especially when FSR 3 won’t be depending on AI unlike DLSS 3 which leverages from both AI and motion vectors which will be missing in FSR 3 as a result of being limited to AMD drivers.
