On 4k Monitor, DLSS @ 1080p runs at lower FPS than Native 1080p

Hey guys, I would like to know if anyone has any ideas on improving my FPS while running at 4k. Using DLSSTweaks I had set my DLSS to upscale from 1080p to 4K, and I get an average of 40-55 FPS doing this. However, if I set the game to 1080p manual full screen resolution, and then turn off up-scaling (setting to FSR with 100% res), my FPS is significantly higher at the 80-90 FPS mark.

Do you have any tips to still run the game at 4k, so I maintain the 4k UI while rendering at 1080p (with DLSS up-scaling if possible)?

Forgot to mention my specs,

I'm on a Razer Blade laptop, using an RTX 2070 and an i7-9750H, with 32 GB of RAM. Using an external 240hz 4K monitor connected over displayport.

Also for context, if I run the game at native 4K, I get around 20-25 FPS.

because it forces dlaa. https://www.nexusmods.com/finalfantasy14/mods/2196 use this to fix it and apply proper preset.

As said before, I use DLSSTweaks to alter my DLSS manually. I have my presets overridden to run the game at 1080p before up-scaling using DLSS (manually set to 0.5, or 50%). I also manually updated the game's DLSS plugin myself. I verified DLSSTweaks is working by setting my presets to 0.1 (or 10%) and as expected the game became a blurry mass of pixels.

Not to mention, if the game were not upscaling, my framerate would not improve at all when using DLSS (as was the behavior before I used DLSSTweaks)

I'd still try to force dlss via optiscaler to have a comparison to dlsstweaks.
