PRIME only works with a compositor.  Make sure you are using one.

I'd argue this is actually a bug (probably in the X server): If PRIME can't
work without compositing, it should enable automatic compositing for the
windows that need it.

Apps using PRIME, or others?

BTW, just xcompmgr -a should be enough, no need for -c.

others.
Today I've tested with DRI_PRIME=0. Same lags. It's appear, when xcompmgr
running.

That's not directly related to this bug report then. If xcompmgr -a doesn't
work better, there are many other compositing managers you can try.
