I have never understood how these kind of questions would solve anything.
There are plenty of topics surrounding this issue. Here is one, which I found doing a quick search in the support section:

As I pointed to you in the xwis forums, you should continue using your quiet well speaking english. I do not know how great your russian audience understands english, but I do however believe you will get a larger amount of views and subscribers if you prioritize the non-russian audience. Russian for me is like chinese. No personal!
I do not understand all the hateful comments on youtube about FreQ/Martin being a noob. He played very well tacticly with no doubts he was playing against, as I can read, one of the best soviet players in Russia. The Snow Valley and Heck game was very interesting imo. Nice to see an allied player actually using allied units instead of mass grizzly tanks.
I would try a different server in --> Options.
Otherwise, try to uninstall RA2/YR completly and reinstall. Then update with Cncnet. Additionally run as a administrator.
I prefer Bandicam, tiny, simple and great recordings.
But my general advice for you, if you want your video to be smooth, buy a new comp/laptop. It is 2017.
