Your GPU Driver is blocked. It means HWA = off.

OK, and here's a somewhat off-topic question: my driver version seems to be what the about:support tells me to update to (8.982.*.*), so why is HWA is off then?

The != means NOT. Though I agree the sentence doesn't make much sense, because the '!= 8.982.*.* or newer' part would mean you shouldn't update to anything newer than 8.982.*.*, which definitely isn't what it's supposed to mean. Someone just put in a variable without checking how it turns out after expansion in the sentence.
