BBloke Posted January 15, 2008 Report Share Posted January 15, 2008 Well I came across an article and thought I would post it here just for your info. It seems to me as though currently PCIe2.0 is as much as twice the speed as was AGP x4 to x8. It'll be nice to see what happens over time with this change of interface.

BBloke Posted January 19, 2008 Author Report Share Posted January 19, 2008 Well it may not seem like much but whilst discussing motherboards and crossfire configs with Quazi the other night. Quote Link to comment Share on other sites More sharing options...

Klinger Posted January 19, 2008 Report Share Posted January 19, 2008 That Intel DX38BT mobo is a tasty bit of kit BB. Do you think Xfire (or SLi, for that matter) is the way to go? It seems like a lot of hassle to set up. Is there a great improvement in IL2 with it? I've heard of cards soon to be introduced, with 2 GPUs. Would that be a better solution for the average gamer? Is there any benifit from PCIe 2.0 to the single card user? Cheers. Quote Link to comment Share on other sites More sharing options...
BBloke Posted January 19, 2008 Author Report Share Posted January 19, 2008 I would say at the moment it's all very new and certainly difficult to say how things will help anyone in the long run. As most things are doubling up its not just 2 x GPU's on one card it's 2 x GPU's on one card running in Crossfire (4 GPU's) and as things are just getting bigger I've found myself concerned not just with graphics capability but what is needed to push those 22", 24" and even 27" screens. I've not really paid much attention on the FPS figures between XFire and single card running albeit in a recent batch of tests it just seemed as though no matter what I threw at it the FPS stayed relatively consistent where IL2 was concerned. Google Spreadsheet FPS Benches What I did notice during my awful time with Stalker and some nasty yellow triangles was that 2 cards were better than one.

BBloke Posted January 19, 2008 Author Report Share Posted January 19, 2008 As far as IL2 goes I get the following: Single card @ 1280 x 1024 2xAA, 16xAF: 39 avg fps Double card @ 1280 x 1024 2xAA, 16xAF: 46 avg fps As soon as I know how to bench stalker and post em up.

Blairgowrie Posted January 19, 2008 Report Share Posted January 19, 2008 I am afraid you are just confirming my opinion about dual cards Chris. I still think it is a marketing scam for the video card vendors to double up on their sales. A gain of 7 fps won't even be detectable in the graphics. I'd rather spend the extra money on a better video card or a second Raptor. Quote Link to comment Share on other sites More sharing options...
BBloke Posted January 19, 2008 Author Report Share Posted January 19, 2008 But then surely the same can be said about dual CPU's for gaming. Quote Link to comment Share on other sites More sharing options...
Blairgowrie Posted January 19, 2008 Report Share Posted January 19, 2008 If you had to buy two separate CPU's, I might agree with you. But you don't! You buy a single dual core or quad at a similar Quote Link to comment Share on other sites More sharing options...
BBloke Posted January 19, 2008 Author Report Share Posted January 19, 2008 With IL2 I agree there is little benefit but that for me is not all I play and new games do grab my attention. Quote Link to comment Share on other sites More sharing options...
BBloke Posted February 10, 2008 Author Report Share Posted February 10, 2008 Just did a small amount of testing to see what happens where (mainly with refresh rate and VSync). Here are some figures: 1400 x 1050 x 32 bit - Water 2, Effects 1, 2xAA, 16xAF - V-Sync Off - CrossFire 2008-02-09 21:54:14 - il2fb Frames: 5269 - Time: 120000ms - Avg: 43.908 - Min: 23 - Max: 121 1400 x 1050 x 32 bit - Water 2, Effects 1, 2xAA, 16xAF - V-Sync On - Refresh Rate 60Hz - CrossFire (x8 x8) 2008-02-09 22:16:07 - il2fb Frames: 4128 - Time: 120000ms - Avg: 34.400 - Min: 18 - Max: 62 1400 x 1050 x 32 bit - Water 2, Effects 1, 2xAA, 16xAF - V-Sync On - Refresh Rate 60Hz - Single Card 2008-02-09 22:20:46 - il2fb Frames: 3498 - Time: 120000ms - Avg: 29.150 - Min: 8 - Max: 62 Notice the minimum FPS and total Frames rendered drops significantly.
