Dirt 2 poor performance with the G73-A1 laptop

Hi all,
I just got my G73-A1, everything stock. I installed dirt 2 and I see very poor performance. I tried the benchmark and I got around 3,800 point and averaged 46 fps. That is bad. I'm using high performance mode.

Any idea why such a poor performance in this game?

 

46 fps are bad? are you joking?

 

Maybe because you're playing 1920x1080?

 

Yes its the 1920 thats killing this machine for me. Im personally waiting for the BB version with Low-Res. When Dirt 3 hits the shelves then what? I refuse to use a LCD without running at its native res either.

I dont think people realize how high of a Res that is for gaming when they want full detail+AA/AF.

 

Look at Quagmire's uploaded videos. They should give you a good estimate on how much you should get on some games. He has dirt videos also I believe.

Quagmire's runs at full setting fine on most cept for like bad company which I would expect since it's not a desktop.

46 isn't bad it's completely playable you shouldn't experience any sort of slow game performance.

P.S. he is running all his videos in the native 1920 x 1080 res.

 

I Was running the game on 1400xsomething, not full 1080p. Compare to my M17x with 280m I was getting avg of 57 fps, so yes this is bad.

 

Well considering specs, the G73 should be faster. Maybe there are background programs running that's stealing performance?

 

Hey guess what?

DirectX 11 lowers framerates

That is at least one reason why your framerates are lower

Drop it to directx 10 and take out one of your 280's and I'm sure the Asus will have better framerates

 

Um..Gtx 280 Sli is > ATI Mob. 5870.... u can't compare ur fps with his if you think about it. Unless the game doesn't use SLI which I don't know if it does or not. I really don't get what's wrong with 46 fps..u could prolly increase it further by making sure nothing else is eating ur speed up by closing all apss or even going lower res? changing settings..

It's all about tinkering with what u have till u achieve desired results.

 

The game doesnt support SLI, it is running with one 280 on the M17x. I dont really get why im having much less frame rate with a better machine.
280m vs 5870
xq9300 vs i7-820QM
4GB ram vs 8GB (same speed)

The g73 is better in every category than the M17x, but why i get much less performance on this game?

 

Other than the fact that the HD 5870 supports DirectX11 while the GTX 280M doesn't and with Dirt 2 being the first DirectX 11 game out maybe the lower performance is due to Dx9 vs Dx11?

 

Yep, as I said on the first page...Dx11 can significantly reduce framerates over previous versions

As you can see even desktop cards run at vastly lower framerates in 11 vs 9

 

I see, thanks for the link and for the help.
Seems to be DX11 puts a lot more stress on the machine and about %10-15 drop in frame rate. I'll try to run the game on DX9 mode if its possible and compare. I honestly dont see any noticeable visual differences...

 

try updating ur GPU drivers and game...

 

The Mobility 5870 is only a bit faster than a desktop 5750 and that is going to be a bottleneck quickly when gaming at 1920x1080. It's not anywhere near a desktop 5870 unfortunately. Which sucks and is semi-bulls$%#ty, but what ya gonna do when laptops would melt with a real 5870.

 

Someone needs to make a laptop that has a plug in slot with a mesh bottom for a full desktop video card, granted the laptop would therefore have to be huge and bulky
