And lets not forget the gpu consists of many different parts that do different things and monitoring softwares are not monitoring every part (it's most likely just keeping an eye on the dispatchers or something) so a 100% load isn't necessarily the same for different games/applications...
Good point. Didn't think of that. GPU RAM usage is different on each Game at least.
Oh yes, good point. On Asus GPU Tweak the GPU Usage can be 99% but VRAM usage is different for different games. Thanks
well i was not really thinking about the vram as it doesn't use much power, rather all the different parts on the chip itself like some parts do the geometry, others do textures and post processing effects like AA/AF and the like (TMUs, Shaders, ROPS and what have you..) If a game manages to put quite even load on all of the parts then that would result in high power consumption as well (for that particular card anyways, the ratios between those rops/shaders and stuff tend to vary a little between different models as I'm sure you've noticed if you check the specs for different cards)
edit
The load% could just be the part of clock cycles when the gpu is doing at least something vs waiting for the cpu to give it more stuff to chew, so a 100% load would just mean the gpu is doing something on every clock cycle rather than every part of the gpu to be fully loaded constantly...
