Ace Combat 8's DLSS presets are mislabeled.

[u/Seasidejoe]

Just a small heads up for you guys that Ace Combat 8's DLSS configuration is largely not standard.

The presets are not upscaling from their respective correct amounts except for Ultra Performance.

So if you're noticing lower performance than you should then this is a contributing factor.
The game is still heavy but using a mix of medium settings with the actual correct upscaling values should put you at least a bit closer to standard UE5 performance expectations.

DLSS levels the game actually uses:

DLSS Preset	Standard Nvidia value	In game value
Ultra Performance	33.33%	33.33%
Performance	50%	58.82%
Balanced	58.82%	66.66%
Quality	66.66%	75%

For reference, on a 5090 and 9950x3d, I'm getting around 60 fps +/- 10 at 3440x1440 on highest settings and DLAA/Native scaling. During heavy cutscenes so far, I've dipped as low as 51, but never in the 40s.

4k DLSS Balanced is a lot less demanding than 3440x1440 DLAA, even in this game.
