GTA4 Crossfire issues

[pgi947]

Hi,

So today I finally got my 2nd 6950 installed (xfx 2gb if it matters). I went to fire up GTA4 to run a benchmark to see what gains I got over the single card setup. Went into the graphics settings to set everything to the highest settings and its locked everything down at the lowest possible settings.

It says something like "202mb/4092mb used, resources are too low" seriously?

I've done a bit of searching and can't find anything concrete, any ideas?

I just found a sweet mod for it this morning too called 'iCEnhancer'

Edit: my setup:- i7 2600k, P8Z68-v Pro, 8gb vengeance, 2x xfx 6950 2gb in crossfire, HX1000

I was under the impression GTA IV doesnt support dual cards, SLI or Crossfire.

I've heard this too, but also I've read lots of forums of people having no issues running the game at high spec with crossfire cards. Surely it cant be a case of "you've spent £400 on gpu's, so were not gonna let you play the game".

Also it ran fine on my old SLi setup (9800gtx+'s), granted it only showed a single GPU in the memory usage (512mb) but it still ran fine and let me select what display properties I liked...

Fixed it, if anyone else gets the issue do this...

Go to the dir folder of the game (for me on steam it was steam/steamapps/common/Gta IV) create a new text file and name it 'commandline.txt' (without quotes), in the text file type '-norestrictions' (again no quotes) and save, boot the game and though the warning about sys usage is still there, you should be able to adjust all the graphics settings. Now if only iCEnhancer worked on .0.7
