You are planning to test the DLSS mod for Starfield, right?
So here are my findings for now.
Three quick tests.
1) Native 4k Ultra preset 100% res, vs ultra preset fsr2, dlss and xess all at 50% res.
2) Native 4k ultra preset 100% res vs dlss ultra preset 60% res, since that's the best the 4070ti can do for 60fps.
3) Native 4k ultra preset 100% res vs native 4k low preset 100% res
I chose this super hard location for the upscalers, since there are many straight lines on the ceiling and a difficult moire pattern.
1+2)
native 4k ultra
dlss50% ultra
dlss 60% ultra
xess 50% ultra
fsr2 50% ultra
3) 4k ultra native
4k low native
Well native is surely better. There is only so much an upscaler can resolve with 50 and 60% res. The good thing is that the vast majority of frames, do not have such contrasts and straight lines.
DLSS is again a little better when moving, but jaggies appear in all upscalers. I am talking about this difficult scene.
Even at low, you can't have 60fps on a 4070ti. Only 44fps lol. The low preset shows little difference compared to the ultra, but this may not be the best scene to highlight the differences.
More testing will take place. I will repeat my initial statement. Without upscalers, the game is mostly unplayable. Sad or not, unoptimized, inexcusable, bottomless pit or whatever you want to call it, upscalers are mandatory for this one.
