It looks like NVIDIA is sponsoring some of the popular MSFS youtubers to push out marketing content for their 3000 series (this and this). I had the 3090 briefly, but ended up trading it for a 6800XT, and never had a chance to do head to head comparison.
I wanted to simulate how my card will perform under similar flight conditions. It’s not really apple to apple comparison as I don’t fly A320, but decide to do a full flight from Munich to Zurich with the same weather condition, and the settings shown in the first video in TBM930 using autopilot.
To even the playing field, I used the same overclock for my 10900K at 5.2Ghz, and my 6800XT overclocked to 2600Mhz running on 64GB RAM.
Here’s how it performed.
Out of Munich: 45fps
Cruising altitude (12000ft): 60fps external, 53-58 in cockpit
Approach: 45-48fps in cockpit
Landing: 38-40fps in cockpit
On the runway: 35fps in cockpit
These are just rough comparison for fun, but it seems like 3090 has about 15-30% advantage when things get intense. Once at the cruising altitude, things even out.
I had my GPU running at about 80% utilization most of the time, so switched to 100 render scale instead of 80, and the fps didn’t change, but GPU utilization went up.
It will be fun to see how other GPUs stack up in similar flight conditions. If anyone has 45 min, give it a go, and post your result. It might help people looking to upgrade at some point although the stock situation really sucks.
One more thing: there was a severe stutter 60 miles out from Zurich. Both times at the exact same place.
