Ok so i crumbled today and bought some new toys for COD.
Have to say after just testing a single GTX580 1.5GB vram at standard clocks and standard driver 280.19 settings it is way smoother than my quadfire ATI 5870 setup. Im taking screenies of black death for comparison of single 580, SLI, TRISLI, QUADSLI.... lll post back soon!!!!!!!!!!! ![]() Last edited by FS~Phat; 08-03-2011 at 03:23 AM. |

Ok and the results are in for single and SLI after i finally managed to get a custom SLI profile to work!
All setting at 1920x1200 2 graphics settings tested 1. Everything high settings and 4xAA with all checkboxes selected vsync off (almost maxed out) 2. Maxed out settings with 4xAA with all checkboxes selected vsync off Firstly what I noticed. The GTX580 in both single and SLI is way smoother than my old setup. (for dual SLI only - see notes below) Only graphical anomaly was in SLI mode with ocassional slight shadow flicker from smoke and very small frame jitter. MUCH SMOOTHER! Likely some more fiddling with more custom settings in SLI profile would all but remove this. An official driver profile from nvidia is the best bet. Final Performance Notes... There is currently no benefit with current driver SLI support and game optimisation going further than a 2 card SLI setup with GTX 580. You get a very minor max increase for TRI SLI and slightly negative scaling for AVG FPS. Negative scaling for QUAD SLI on both AVG and MAX. You need mega power supplies for QUAD SLI! Nvidia 580 has the edge for less big stutters and pauses compared to the ATI 5870 in SLI/Xfire but Nvidia has a noticeable microstutter and surging with anything above 2 card SLI. Compared with the ATI 5870s which have some bigger hiccups and pauses but they are generally smoother. Nvidia is quicker to settle with scene changes when changing internal and external views with very minimal texture draw delay and stutter. 5870 QuadFire seems to scale a little bit better in terms of MAX and AVG FPS compared to NV QUAD SLI... with the caveats below... Overall both SLI and Xfire are not officially working and both required work arounds which are not optimal so there will be further hope for future driver profiles and game optimisation. Image Quality Notes Anti Aliasing looks better on NVIDIA but not for everything. Mind you I was using standard driver settings so it might be possible to tweak AA quality a bit. Final conclusion... A dual SLI GTX580 setup would appear to be the optimal smoothness and performance with current drivers and game code at 1920x1200 res. OK some stats and pics Single 580 on high avg 52 max 98 min 14 SLI 580 on high avg 64 max 152 min 6 TRI SLI 580 on high avg 60 max 146 min 9 QUAD SLI 580 on high avg 55 max 142 min 12 Single 580 Vhigh (Maxed) avg 48 max 94 min 5 SLI 580 Vhigh (Maxed) avg 58 max 144 min 18 TRI SLI 580 Vhigh (Maxed) avg 56 max 139 min 9 QUAD SLI 580 Vhigh (Maxed) avg 50 max 134 min 8 Single 580 High ![]() Single 580 Vhigh (Maxed) ![]() SLI 580 High ![]() SLI 580 Vhigh ![]() TRI SLI High ![]() TRI SLI Vhigh ![]() Quad SLI High ![]() Quad SLI Vhigh ![]() Last edited by FS~Phat; 08-03-2011 at 03:17 AM. |

OK so Quad SLI took a whole lot more work to get going but not because of the game. System power load was way too high and even running everything at stock clocks it kept doing a hard shutdown when ever i started anything 3d.
I have a 1250W supply that wasnt enough, so since I now have space in the Mountain Mods case I've brought another 1200W supply out of retirement and installed it. The MotherBoard also needed the second PCIE 12v molex just to be stable at my standard CPU overclock of 4.6Ghz. End result is Quadfire now works with 2 cards on each power supply and the 2nd PCIE molex to MB. These GTX580's suck some serious power! Ill post the results above so its all together.... |

No fps gain from tri or quad at your res?
Could there be any improvement from tri or quad if you force really hard AA methods in drivers and/or double the resolution? There should be a way to shrink a larger game resolution to actual size of the monitor somehow. This will produce a nice AA effect. (There is an option for this in ArmA2 for example.) |

Great!
I recently tried resolution 1920x1080. Sim runs better. I'll try to post a snap.
