A few more tests if anyone's interested.
Daymare 1994 seems interesting, since it features all, dlss, fsr and xess in all their settings. I am testing native vs balanced, since this is my go to solution. Seems ok to me, for the distance I'm playing.
I chose this scene since it has grates on the floor, some lights, one of which passes through the grates, a yellow/black texture on the door with an angle, some cables, a close model (the protagonist) in the foreground, etc, thought there are quite a few things for the upscaler to resolve.
Native 4k 253W
dlss balanced 94W
fsr balanced 80W
xess balanced 102W
First of all, the upscaled results are really good. Fsr and xess retain more color and dlss seems a little washed out. However it is doing better with the fine details of the grates, if you look in distance. xess is also good with the grates and retains the initial color.
The differences between the upscalers are not substantial and all do a very good job. What IS substantial however, is the 150-170W difference, compared to native. The retained image quality is bonkers, for the power draw saved.
You can see that the 4070ti is almost at its max for 4k native. The significant power draw saved, means that the upscalers, open up 4k/dlss/xess/fsr balanced possibilities, for much lower grade cards and that's why I love them.
Also the vram savings are substantial. Xess in particular, saves a whole 2GB vram in this scene. Actually it goes from 8GBs are not enough, to...ahem...8GBs are enough. xD
I find it weird that Xess is consuming the most power, compared to the other upscalers. I mean dlss is supposed to use the tensor cores and these are not running on air I guess? For this static sceme, Fsr is the middle ground in image quality, power draw and vram savings, and for a purely software solution, son I'm impressed.
However I tested motion in this one too. Here's the vid. Same thing, native vs upscalers balanced. (non monetized channel since 2006)
I am not sure if the video can highlight the differences though. It was recorded with an external recorder, which is 1440p/60 capable, but the recording was done on my 2500k which can only do 1080p/60 without stutters. It then was upscaled to 4k for better bitrate.
Anyhoo, again all upscalers are great. fsr more defined, dlss more accurate but somehow I think xess is the better middle ground.
