Hi,

I have the following PC:

AMD Phenom II 965 BE X4
2x HD 5850 1GB VRAM
G.Skill 2x2GB DDR3-1600 F3-12800CL8D-4GBTD
Asus M5A99X EVO AMD 990X+SB950 ATX

Is there any way to benefit from crossfire to run the HD texture pack. Buying two more modules of RAM would improve performance?

It′s unplayable now.

Thank you.

There is, you have plenty of VRAM.

What do you mean by 'unplayable'? Below 30 fps at max settings?

1Gb should be enough, I say should. Depends on other settings and other mods you use.

Most of why the texture mod troubles most systems is these high end textures take up a lot more vram space.
Cross-fire doesn't give you more vram space, since it is mirrored, just better performance as it balances the load.

So if it is able to run the game, without any artifacts or purple textures, but is abit slow, yes getting cross-fire to work will be of a benefit.
If you are seeing purple textures, your vram is running out and adding more system ram is not ideal, but could work in replace of it.

Biggest benefit will come if any improvement can be made to your processor, over clocking that will provide the biggest benefit, if you already are, I'm not sure why you experiencing any problems. Unless you've got Shadows on ultra, which is a huge processor killer.

just make sure your running 64bit windows ...... i'm seeing more and more people complaing about CTDs and such and the number one common factor among them all is that they are using 32bit Windows xp/vista/7.

The only other reports.. which are very rare, are performance issues, mostly due to running on a machine with less than the recommended requirements... such as a 512mb video card.

I′m running it on Windows 7 64x, anyway, I′ll Overclock the processor in order to improve performance.

Thanks

When I ran it with crossfire enabled it tried to use over 1900mb of vram, without crossfire it was using 976, i still have more testing to do but you could try disabling CF
