Sharing some info again.
1. For monster hunter wilds, when in the camp screen (with the palico), the fps was consistently 180-190 max (highest setting, raytracing highest, 4k, frame gen on). P/S this game not supporting multi frame gen
2. I used the Nvidia tool to force DLSS4 (Set it to use the latest DLSS instead of the DLSS3.7 shown in the in-game option). After done, the same camp screen with Palico increased to max 220-225 consistently (Every time i went in the camp, i stopped there monitor the frame rate)
3. After some time, I proceeded to adjust the HDR setting with contrast, brightness, etc. After done, noticed the fps consistently reduced to 205-208 max.
DLSS4 increased around 35 fps with frame gen, but after adjusted some HDR settings, the fps dropped around 20fps. Anyway, at least still increase around 15fps at the scene.
P/S MHW has an area with optimization issue or buggy, walked to that area, fps would dropped 40-60 fps, walked a few step away from it, fps will back to normal. And that area that causing the fps drop has nothing special, just a road with nothing.
If not mistaken dlss4 is focus graphica quality. But extra mfg for 50series card
