EDO and AMD FSR, more FPS.

FDev have put FSR in to EDO as a way to bring performance up.

For those who don't know FSR is an AMD technology which renders at a lower than native resolution and using alsorts of clever stuff up-scales its back to native resolution for the screen at near native image quality, the benefit is higher FPS for a slightly degraded image quality.
That's basically DLSS, a similar Nvidia technology, its not 100% as good as DLSS 2.0 but very good in its own right and unlike DLSS its very easy to integrate in to games, and FSR doesn't care if your GPU is an AMD one or an Nvidia one or how old it is, as long as its a Maxwell / Ellesmere GPU or newer (Nvidia 900 series / AMD 400 Series)

In the link below i have a couple of comparison slider images.

Below that are the raw images so you can compare the FPS difference

Settings are 1440P with all the graphics quality setting at their highest.

Ryzen 5800X / RTX 2070 Super.

FSR off vs FSR Ultra Quality. use the slider to to slide across the two sides.

The lighting is not the same in the two images, because the light changes every few seconds and its impossible to change the FSR settings in the menu before the lighting change cycles.

There is a small image quality degradation, but in return you get an extra 58% in FPS.

Its a shame fsr doesn't work for me, the higher to quality setting i choose the less it utilises my gpu, the fps stays consistent.

In trying it with game resolution at 4k, even performance keeps fps similar, may be 1 extra frame.

Weird.

That sounds like a CPU bottleneck, what CPU is it?

Or it could be V-Sync, do you have that enabled, what FPS are you getting?
 
Nope not at all, cpu is 15% used, all checked out. Even power limits not causing it.

I got 14 cores with 28 threads

It mainly happens at settlements

Ok, what about V-Sync? V-Sync locks your Frame Rates to 60, if it can't get to 60 it will drop to 45, or 30.

As I predicted, FSR (and DLSS) compensates high rasterization workload (GPU bottleneck), not the spam of inefficient draw calls (Which is a CPU bottleneck).

Yes, its a GPU thing, not a CPU thing, Rasterization (GPU) Draw Calls (CPU)

EDO doesn't seem heavy on Draw Calls but weirdly high on Rasterization, with FSR off i'm sub 60 FPS in stations, even less on settlements, at 1440P with an RTX 2070 Super loaded at 100%
 
And yet turn it off, gpu uses 99% or 100% and I get more frames. So fsr for me feels pointless
At least dlss has tensor cores to give a bit of a boost.

Shame fsr cannot tap into this additional resource
 
I'm surprised you don't need to install something to enable fsr etc

Or we do, and its built in with game install. Maybe fdev has messed it up.
 
FSR works at the game engine level, it uses the standard FP compute abilities to work which is why it works on any modern GPU. It just doesn't require specialised hardware. IE Tensor Cores.

I haven't tested the difference on settlements yet, i might find i have the same problem you do, if i do its not a fault of FSR.


I have read analysis like this on EDO before, its interesting but i don't want to get in to all of that here, all i want to do here is show people what FSR is and how people can benefit from it.
I may have to do more of my own investigation to see if i have the same issues @ebbrell does on settlements.
 
For me, the FSR didn't make the performance better and using it leaves a horrible image. On top of that, it removed the options that previously existed (CAS) which allowed an excellent image quality. Current alternative options to FSR now make performance much worse than before and image quality is much lower than before.
 
FSR will only marginally gain FPS if your GPU is already struggling, which would be the case if you are below, within or slightly above recommended specs (GPUs around computing power of a 1060 6GB or a RX 580 8GB). It does not help on CPU bottleneck which is the case due to the inefficient draw calls. FSR (and DLSS as well) reduces the rasterization work up to a quarter and fills the gap using machine learning. It won't help if the GPU is forced to idle because the CPU didn't yet send all required instructions.
