I tried that made little difference . When doing nothing the game peeks 80% GPU usage but in combat low as 20% usage .

SSD
8GB ram
GTX680 Sli Gigabyte Factory overclocked
Asrock Z77 Extreme4
PSU 850
i7 3770k
SAMSUNG S27A950D Black 27"

My card does this kind of thing even w/one card, so it's not strictly an SLI issue. This sort of thing is really common with games that are brand new, ESPECIALLY w/games that utilize hardware PhysX.

Something to keep in mind is that gpu usage that is incurred due to PhysX is not 'counted' in your GPU Usage if that card is also doing rendering. IOW, unless you are looking at usage on a card 'dedicated' to PhysX, you won't see the usage % that is due to physX.

So if 70% of your cards capacity is occupied with rendering, and 30% is occupied with PhysX processing, AB/PrecisionX will report to you that the card is at 70% usage. If you then throw in a dedicated physX card, you'll see the 30% usage showing up on that card. Your main card in that situation may or may not then jump up 99% or thereabouts.

Honestly I've tried pretty much every hardware-enabled PhysX game that's ever come out, and there are ALWAYS issues with GPU usage when you run them, even WITH a dedicated card. It's kinda like as soon as you see that a game implements HW PhysX, you should pretty much ignore your GPU usage readings moving forward, because almost no matter what you do, you won't be getting 99% on any of your cards.

I was messing with Borderlands:2 . After some tweaks I could run BL2 high physx settings but sacrificed other settings .


Ambient Occlusion- off
View distance- low
FXAA- off
Texture quality - low

Every other setting is high . I believe sli not even working since FpS produce the same results with or without single or Sli GTX680 setup .

using the i7 3770 do I need a better CPU if I want higher FPS ?

I dunno about whether SLI is working in BL2 cause I only have one card. But I played the whole game, start to finish, with all the settings completely maxed (1920x1200), including physX, on my 670 and I think the lowest fps I ever saw was about 35fps, which was still totally playable. You shouldn't have to sacrifice any settings on ONE 680 (let alone on two in SLI) to get that game running great.

This game is so cartoonish that I'm surprised it even gets my GPU to 50%. It came with the card and thats why I'm even playing it.

Playing on a 560 sli in surround, at with 306.23 WQHL at 3840 x 720, All Max except No AA, no ambien occlussion (20/30 fps cost), no physix, I was doing about 70 / 80 fps, in open areas, with some punctual 90s, in combat mantaining 70 fps and in vehicles drops to 40 fps ,

Yesterday I upgraded to 306.97 WQHL.... and my surprise: from 20/30 fps gained!.... With same config, about 85/100 fps, in combat 80/90, in open areas some times as high as 130/140 fps, and in vehicles not less than 60 fps.

Gentlemen, upgrade your drivers! thumb.gif

Could my problem be memory leakage ? I have tried OC that made a small difference at 4.3 . Even OC the cards a bit with little improvement . Some areas the game peeks 380 frames but the majority of time its 80FPS down to 30 FPS .

Odd I force CPU to run Physx and borderlands still produces the same results .
