@aplinlol, thanks for the answer. Yes, the problem was indeed with the buffering. If there are still massive problems at 2000-2500 bitrate, what amount should I use to minimize the issues, while keeping the decent quality? And does it apply both to bitrate and buffer size or just to bitrate? Would it help if I switched to 60 FPS (i have a decent CPU - i5 4690)
Your equipment and bandwidth look good. Like
alpinlol said, streaming at 3500 on twitch is not a good idea for anyone that is not partnered. On the other hand your
CPU is good enough to go up a preset or maybe even 2. Test your CPU usage before you decide whether to go Faster or Fast. In all honesty, this doesn't provide near as much quality increase as it does CPU usage, lol. I'm gonna suggest a different approach, only because
alpinlol had suggested the 48fps / 1800 / Fast Preset.
If this does not give you the outcome your looking for, try lowering your
FPS to 25. Bitrate 1800. 720p. Fast Preset. This is possibly a better outcome depending on the game.Lowering the FPS requires less bitrate to provide a little better quality. If the game is low motion/action, the FPS wont be noticed. Now if your playing COD or some fast paced shooter, 25fps may be noticeable depending on the bitrate/resolution and preset. This is just one of many possibilities and playing with numbers is your best bet at finding what gives you the best outcome.
I hope you find your niche for the settings. Takes a while but eventually you get that perfect medium. Hopefully, lol.
