Is it normal for GPUs to go up to 99% usage in BF3?

As the title says i have been monitoring usage on my 7970 as i get lag every now and a game but have good ping and over 100fps on medium quality and my CPU is i5 2500k @4.4ghz just wondering why i stil get a bit of lag, would capping or v-sync help?
Thanks

Try turning v-sync on and see if it helps I guess?

I appreciate the reply but doesn't that cause mouse lag? i have a 120hz monitor
Its strange it has been smooth so wonder as well if it could be there end or im getting spikes for some reason.
Also will capping at say 80fps cause less stress?
Thanks

In game vsync on bf3 is really good for me no input lag at all (660ti)

Could possibly be your 2500k as bf3 online is very cpu heavy. I would try online with something less cpu heavy like an outdoor map and see if it still does it.

Also check pingtest.net for packet loss or jitter. http://pingtest.net/
You need 0 packet loss and jitter of less than 5.

Yeah but its been fine for a while with my cpu so seems something new also i use pingtest and that seems fine just bugging me a bit thanks

Since the GPU is the prime determinant of the framerate you get in a game, you would want the GPU usage to be the highest possible as that would mean that there is nothing bottlenecking the GPU itself. The GPU is the bottleneck (ideal scenario).

99% means you're getting the expected performance. You might have been alarmed because prior to the AMD Catalyst 12.11 Beta drivers, GPU usage in BF3 was less; well, now, it's been given the needed performance boost and that's why you see that high GPU usage.

Ok thanks using HWinfo64 it's saying CPU is around 75% usage.

Hi thanks for all the replies, after some googling i found out if you cap your fps or use V-sync your cpu usage goes down. For instance if i cap at 70fps on high my cpu usage goes down to 58%-65%, thought i would add that just for people that didn't know.May come in handy when using capture programs.
Thanks
