Question / Help Stream is still blurry-ish

[DigitalFYB]

I've been streaming to Mixer with OBS for some time now and I've finally decided to reach out for some help! I've gotten to the point where I can use 1080p/60fps but realise in that same breathe there is other settings that work just as well. I had a question as to how I can get a very crisp and clear image on mixer side (in that quality im looking for)

PC Specs:
AMD Ryzen 7 2700
GeForce GTX 1050 Ti 4gb
16GB Ripjaw Ram & 500GB SSD & 500GB HDD

I'm thinking it might have something to do with the lack of a capture card, seeing as higher end ones have 4k capabilities.
Will also be upgrading to a RTX within the month.

You can checkout my usual streams which will give you an example of the blurryness I'm talking about.

Increase your bitrate. 2500 isn't enough for 720p. Guidelines from Twitch: https://stream.twitch.tv/encoding/
Other anomalies:
- either stream at 30 or 60 fps, but not 48. 48 is uncommon and results in non-smooth video at the viewer, because the viewers' monitor refresh rate (usually 60 Hz) isn't a multiple of the frame rate
- don't use "rescale output" in the encoder settings to rescale to 1280x720. Instead, go to Settings->Video and set the output resolution to 1280x720. Leave the canvas size at 1920x1080. This way rescaling takes place on the GPU and uses much less system resources
