GPU's Utilization ?

[stuntmanSLim]

Why does the GPU's utilization drop to approx 35% when you put the "view distance" to maximum playing Arma 2:OA,but if you bring down the view distance,the gpu utilization increases ?
There is plenty of Vram/monitored,so it can't be not enough vram,could it be not enough Vram bandwidth ?

Arma 2 with view distance set ingame to maximum will crush the 680's performance even more than this performance screenshot shows,so therefore Arma 2 & 3(upon release) running on a 680 with 2gb vram will be upsetting for the owners. Two 4gb/680 or Two 3gb/7970 is required...

Sadly my 680 can't play it

CPU bottleneck? As you increase draw distance your CPU will need to process more information.

Why not ? one 680 should still run it at reasonable settings.

 

[Gregster]

You missed my sarcasm

The view distance is adding more detail to a closer view I would imagine, so the higher distance view is using less detail?

I don't think its CPU bottleneck coz the cpu usage is only at approx 30%

(I rectified the questions,sorry for any inconvenience)

Why does the GPU's utilization drop to approx 35% when you put the "view distance" to maximum playing Arma 2:OA thus making the fps drop,but if you bring down the view distance,the gpu utilization increases thus increasing fps ?
There is plenty of Vram/monitored,so it can't be not enough vram,could it be not enough Vram bandwidth ?

This review goes against what you are asking?

Makes no sense that increasing the view distance gives more fps

You not read my post correctly,i saying "increasing the view distance drops the gpu utilization to approx 35% thus lowering fps". Thanks for the link,its shown me the fix.

ok thx to Tealc & gregster,you are both right,its CPU dependant. Thanks a lot. I need 6 core ivybridge E

 

[Gregster]

IVY not badly priced.

Still doesn't explain why CPU usage sits at 30%
Maybe this game doesn't work on more then 1 core...

I not sure why the cpu only sits at approx 30% in use,but i did study all 8 cores usage & its spread across all of them variously/multi threaded engine. I think the cpu processes as much data as possible in a very short period of time,the CPU frequency is the bottleneck.
