Hi,
my base canvas resolution is 2560x1440(2k) and I have for output 1600x900(900p) for Twitch (it´s a FPS game).

The other options, are:

Downscale filter: Lanczos(should I use better Bicubic?).

OUTPUT
=========
Encoder: Hardware(NVENC)(new)
Rate Control: CBR
Bitrate: 6000
Keyframe Interval: 2
Preset: Max Quality
Profile: High
Look Ahead: not selected (better this way?)
Psycho Visual Tuning: selected (should I deselect it?)
GPU: 0
Max B-Frames: 2

The thing is, that as Twitch if you are not partner, restricts you to 6000 max bitrate, I normally see grass sometimes a little bit blurry (I see it perfect when I'm playing). It´s just the quality of the stream, that I would like to improve, and I don't know if changing to "Bicubic" instead of "Lanczos", or having Look Ahead selected, would improve it.

What do you recommend?.

Also, one last question.

Using a dedicated capture video card (like integrated ElGato HD60 Pro for instance), would improve streaming quality?.

Thanks
