Hi

 

Id like to clarify this once and for all please;)

 

Im gonna be buying an ATI HD4870 1gb to play DCS:BS almost exclusively.

 

Is there any performance benefit to going to a hD4870x2?

 

Most users have commented that Lomac/BS do not support SLI/Crossfire but I wonder if higher levels of AA/AF eye candy options are available 'for free' so to speak (No FPS hit) with a dual card.

 

Would users of a 4870x2 (preferably running at 2560x1600) please comment on whether turning off the second core of their cards affects FPS/AA/AF/Graphics options in any way?

 

I realise this might be a niche group but I only really need one definitive post and answer;)

 

 

Ps. Yes i know DCS:BS is cpu limited. Yes i know the GTX280 is the fastest single chip card. yes i know the GTX260 216 is a great deal....but this question relates only to 4870x2 at 25x16 only please!

 

Pps. happy new year.

Not to sound like a bother but... I have dual core and the sim runs better when the affinity is set to 2 CPU's and I am running a 8800m SLI (twin chip single gcard) with 1000meg. If I disable either the sim crawls.

I have a 4870x2 on a 27" @ 1920x1200

 

I did some test runs to check it out here are the results.

 

1. Cat AI set to standard ( default ) , both gpus ran at about 30% usage

Cpu usage was about 70%

 

2. Cat AI set to advanced , both gpus ran at 30% again but frame rate was less consistant and more stuttery ( not good ) , cpu usage 70% as before.

 

3. Cat AI to off ( crossfire off ) , single gpu ran at about 60%ish , cpu usage about 70% as before.

 

Heres the kicker , the frame rates on all modes ...... were about the same , with advanced showing some stuttering. frame rate was between 40-60 on average but got real low in towns sub 20-fps

 

With both the GPU and CPU not getting near 100% I would say that game is neither gpu or cpu limited , but poor programming / optimisation limited.

 

I tried manually setting some AA on 2x , AF x2 , it didnt drop the frame rate much 1 or 2 fps.

 

My thoughts , once I get my GTX280 back from repair , I will be getting rid of this 4870x2 , the card is good but not great certainly not £370 great.

I am not alone in this opinion , I have read several other posts with people going from GTX280 -> 4870x2 -> GTX280 again.

 

The gtx280 gives me better performance on most games I play and the frame rates are far more consistant. The 4870x2 is good on paper and on

benchmarks but is lacking in actual game performance.

It is nice to hear the opinion and thoughts of someone who has actually owned both of these high end GFX cards.:thumbup:

Thanks. Thats really helpful.
