2xHD6970 Crossfire

[mavtias]

Well the game wont work with my specifications with Crossfire;

 

Intel i7 920 @ 2,66GHz (Stock)

8GB DDR3 2000MHz RAM

160GB SSD 285/275 (read/write MB/s) - I have Windows 7 Ultimate 64-bit & Grand Theft Auto IV (brand new)

2x PowerColor RADEON HD6970 2GB GDDR5 CrossfireX (brand new)

 

Well I kinda bought these cards and the SSD for the game to run well.

But It doesn't let me change my graphics settings and It's stuck at 800x600 and everything on the very lowest settings.

 

If I disable Crossfire I can run the game fine on max settings, but then It's at 30-40 FPS with some mods, and I can't use

mods like ENB to enhance my graphics, which I want to.

 

Running patch 1.0.7.0, original game (not pirated)

 

So, no;

- It's not my CPU

- It's not my RAM

- It's not VRAM

- It's not my HDD

- It's not the drivers (latest)

 

I know people have had issues with Crossfire but have seen videos on Youtube with people running the game with Crossfire with

no problems what so ever.

And yes, It reports the wrong amount of memory, but I couldn't see that as the "real" problem though.

 

-avaliablevidmem 0.5 (or w/e) in commandline.txt does let me change my settings, but It doesn't matter because It

doesn't change the fact that the game runs like sh*t when It should run everything on max with any graphics mod avaliable.

 

Anyone know the solution to this problem? Because in every thread they say to add the commandline.txt thing, but It

doesn't help very much..

 

Thanks in advance.

GTAIV does not offer any extra performance in CF. In fact, it usually runs worse in SLI/CF configurations.

[mavtias]

Well, that aint true since I've seen people have It working, and since you mentioned SLI aswell I'm sitting in the same room with my friend

who runs SLI and he has doubled (literally) his performance on GTA 4.

 

So I don't think It's a problem with the game, but with the driver/application profile, but I need to know If someone got It working with Crossfire and how they did it.

[mkey82]

GTAIV does not have any benefits SLI/CF.

 

And a big fat LOL at doubled performance in your friend's case.

Good luck with that then. I'm yet to see a single topic on this forum where someone managed to get better performance out of the game with SLI/CF.

Exactly the same statement I made in my first post, hence why I ask.

What do you mean Lol? I can record and upload a video if you need proof...

Ofcourse It doesn't work at double performance ALL the time but UP to double performance compared to before...

Isn't the fact that there aren't many or any people who have got the game to run properly with CF enabled enough proof to conclude that the game is poorly optimized for SLI/CF configurations?

 

I can understand why you feel that the game should run better but you're fighting a losing battle here. If only Rockstar had optimized the game better, you wouldn't have had any troubles.

I don't really think It's Rockstar but AMD that should release better drivers - some say that switching drivers to older versions makes It better, but I have no idea if those versions support the latest cards.

Since GTA4 seems to work with SLI perfectly well I don't see why It can't be done with Crossfire, therefore I think It's AMD's problem, not Rockstar's.

Not really. I wasn't just talking about CF. Irrespective of Nvidia or ATI, GTA IV suffers when you have 2 video cards running parallel.

 

Out of the many GTA players, there might be a handful who were lucky enough to not have their performance affected badly by SLI/CF. This is not a Nvidia or ATI issue as all other games that are properly optimized to run with SLI/CF run just fine. It's only GTA IV that suffers. Doesn't that tell you something? It's Rockstar's job to optimize the game properly. No amount of drivers and tweaking is going to help if the game just doesn't cut it.

 

Anyways, as I said before, good luck to you. You can carry on in the same vein trying to find a non-existent solution or just accept that fact that GTA IV runs better with a single video card.

Well my friend is one of those people who got It working really well, and It makes me jelaous

But since It does work for those people - really well - wouldn't you think It can be the application profile that needs to be optimized for more system hardware configurations for that particular game,

since every game has It's own Application Profile?

 

Sadly, we can't change the application profiles ourselves since they seem to be encrypted, atleast I read so.

I mean when It does work It works really well, obviously. So It could be ATI/Nvidia that needs to improve their application profiles or Rockstar that needs to make their game work better.

But since the game works perfectly well with one card - and crossfire/sli is to make two cards appear and work like one card, I doubt It's mainly Rockstars issue, but a SLI/CF issue, since the game itself shouldn't recognize and optimize the two cards, really. That's the application profiles provided by the GPU manufacturers job.

GTA IV does not support CF/SLI properly. Not one single person that posted here in the past few years has claimed they had any performance benefits from multiple card systems. Most of them, in fact, had problems (worse performance, shadow issues etc.) so yeah, I would like to see a continuous video of GTAIV running on your friend's computer with FRAPs showing FPS in the background where in two consecutive runs you change nothing but disable/enable SLI.

 

This is not an ATI fault, this is not a profile fault, it's all related to the game itself. Full stop.

He just got the two cards so we haven't done alot of testing, but depending on where he are in the game he can get up to 120FPS, which is never the case with SLI disabled.

I will see what I can do ^^

Post a video and we'll trust you.
