Test conditions:
UWQHD, High-End, TAA, DLSS/FSR deactivated, A320 v2, 12:00 UTC, scattered clouds, traffic, 120s frame time
Results: In my opinion, a pretty impressive result for AMD, considering the price difference. The 9070 XT narrowly beats the RTX 5080 by 3-5%. Results are at stock clocks and represent rasterized performance.
It would be interesting to see whether even the 5090 offers advantages performance wise. It looks like my setup runs into CPU limitation due to the resolution. My experience due to benchmarks in FS2020 shows that GPUs got only pushed to their boundaries in 4K resolution.
I have a 5070Ti, and the only reason I would consider a 5080 is to get more processing cores, especially tensor cores which enable DLSS to do its thing. With prices the way they are, this upgrade would cost more than it is worth to me today, so I will wait for the rumored “Super” cards to get both more VRAM and more tensor cores. So no, not based on only rasterization.
You can have this now using Lossless Scaling from the Steam Store. It works just fine on my RX9070. The only issue is that you have to enable it each time you start MSFS, but that is just a quick keystroke. I bought it to enable frame generation in MSFS 2020, but liked it so much I disabled FSR in MSFS 2024 and use Lossless Scaling there as well. Very small outlay to acquire, and the bonus is it works everywhere in Windows if you want it.
In my opinion it makes no sense to compare different results. Therefore comparing DLSS versus FSR wouldn’t make sense to me, since you get different picture quality.
I try to avoid upscaling, since I’m not happy with the image quality in terms of font readability. But DLSS4/FSR4 changed it definitely for the better.
