it is normal no gpu can currently saturate a pci slot

Depends on the game, and if the display driver has crashed or not..

When the driver crashes usage will be maxed but it'll be basically operating at 2D performance.. so it varies.

hmm okey, but look at this https://www.youtube.com/watch?v=3pPBVh7YEmk

He have 49% bus usage.

in Far Cry 4 I have max 4%....

that gpu is rather old it wont saturate any pci slot

99% load in other words is saying that the GPU is bottlenecked, meaning the graphic settings you have enabled are maxing it out. probably from a VRAM standpoint rather than the GPU as a whole.

for example look at this https://www.youtube.com/watch?v=rS1yh238e4c
99% of GPU load and 48% Bus usage ...

lowest settings in FC4 and BF3 still have 99%gpu load, 0%bus usage

[_I_]

bus usage is how much data is being sent to/from the gpu
if the gpu usage is at 90-100% its fine

if the bus usage is hitting 90-100% and the gpu load is under 90% then you have a problem

thank you guys for help :D
