Arc control is suddenly reporting that rebar is disabled, even though I have made no changes to my hardware or BIOS config. I did upgrade drivers to 4575 recently.
I reported a similar issue a while ago in the thread linked below. A BIOS update resolved it then, but now the same issue is back.

The thing is, so far I haven't noticed any difference in performance. Is it possible that Arc Control thinks rebar is off even though it is actually on? Is there any way for me to test whether rebar is enabled besides Arc Control?
