Hello guys,

I've recently gotten into streaming but I'm not satisfied with my quality.

If you take a look at my VoD it's hard to make things out when it's going a wee bit fast in NFS.

I'm streaming in 720p @ 60fps with the help from dxtory. I use these settings although I do not record, just use directshow output:

This image is taken from this guide.

All the feedback on how I can improve my streaming is appreciated and I will try to test the different suggestions and post a short (~3 min) video of the new settings you suggest.

i would recommend using obs game capture rather than dxtory..

about the quality issue. you can use a bitrate of 4000 for more quality but the connection to your current twitch server is not optimal. pick a closer or different server first. see if you get no frame drops.

also it would be a great idea to lower the quality value to 8 since it's a racing game and requires more bitrate to look nice at 10.

I increased the bitrate to 4000 and changed the quality balance to 8. I also used game capture instead of dxtory this time. This is the result.

I also changed servers to frankfurt and got 0 dropped frames according to the below log (if I read it correctly):

However. It still looks really grainy when going high speed. So I guess my next question is how can I improve the imagequality?

And thank you for your input.

Personally I think it looks pretty good. But if you absolutely must have better quality, you can choose a slower x264 preset below veryfast (such as faster or even fast). However, this will significantly increase your CPU usage, so use at your own risk.

looking at the vod and log i can see that the stream quality has improved and the frames are more on time than before

more bitrate would mean more quality.. but you have to consider your viewers connection also.. lower the quality to 6 that should further help with the high speed quality at the cost of low speed's quality

I changed the x264 preset to faster which will only work on certain games because I'm between 90-100% cpu usage so might have to use veryfast in some games. The quality balance I lowered to 6 and this is the result



Personally I think it looks better overall. I might increase bitrate slightly but other than that is there anything else I can change or am I closing in on the possible quality I can get with my setup?

As always, thanks to you both for your input. Looks way better than my first video and less framedrops.

the thing is you're lagging a bit of frames so changing the preset will make you lag more frames. if you're willing to trade the fps for the "faster" preset that would do (not worth it though)

something like 30fps with "faster" preset forget about fast .. but i would rather just keep the 60 fps with veryfast 6 quality, it looks fine and your settings are optimal.

Yeah I see what you mean. I will be running with veryfast for now. I'm getting an i7 as soon as I get some extra cash and that's when I will start using "faster". I was just thinking that I could probably use "faster" in games like League of Legends or some older games that barely use any of the processingpower in the i5.
