Thorburn Posted February 25, 2008 Report Share Posted February 25, 2008 Please take SLI and shove it up your arse. I've been trying to get results for the 8800GTS in SLI with Enemy Territory Quake Wars for the last 3 hours and I swear if it crashes and corrupts the hard drive image one more time I'm going to throw the whole damn rig through the lab window.

Waylander Posted February 25, 2008 Report Share Posted February 25, 2008 No No - just throw it up the M6 to me. I'll suffer it off your hands.... Link to comment Share on other sites More sharing options...

Waylander Posted February 25, 2008 Report Share Posted February 25, 2008 okay - admittedly I came across as a bit more of a rottweiller than I intended there! Sorry! So what did you mean then...?! Link to comment Share on other sites More sharing options...
Cupramax Posted February 25, 2008 Report Share Posted February 25, 2008 I think he was inferring that your 6720 posts have all been in about 4 threads Link to comment Share on other sites More sharing options...
Waylander Posted February 25, 2008 Report Share Posted February 25, 2008 Be fair - 5 threads. That is why I am branching out now and creating more and more threads Once in a blue moon I even venture north of the LoJ....I just get nosebleeds that high up though.

Thorburn Posted February 25, 2008 Author Report Share Posted February 25, 2008 Can we get back to talking about how much I hate SLI? Resorted to running single tests on both the 8800GT and 8800GTS rigs as batching them means every crash means I lose two or three runs Link to comment Share on other sites More sharing options...

Thorburn Posted February 25, 2008 Author Report Share Posted February 25, 2008 I have a little script I wrote to run my tests all at once with no user intervention, but when the machines crashed I'd lose the other results from the test Link to comment Share on other sites More sharing options...

ChadW Posted February 25, 2008 Report Share Posted February 25, 2008 Really stupid set of affairs when old SLI (a la 10 years ago) worked out the box fine, had 2 Voodoo2 cards linked up no probs. Get the impression SLI now just does not work unless the actual game source code supports it let alone the drivers! Link to comment Share on other sites More sharing options...

[runs to hide!] [/ QUOTE ] Worth asking Script works fine with NVIDIA cards with SLI disabled, and with ATI cards both with and without CrossFire. It's just a batch file that starts the game with certain parameters to run my benchmark, looping through for the resolutions I specified and reading the results out the console log. Also the game crashes with SLI when just playing normally Link to comment Share on other sites More sharing options...
cruiser647 Posted February 26, 2008 Report Share Posted February 26, 2008 I thought the cards needed to be the same for SLI to work properly..... Link to comment Share on other sites More sharing options...
Thorburn Posted February 26, 2008 Author Report Share Posted February 26, 2008 Yep, I have one rig with 2 x Gainward GeForce 8800GTS cards and another with 2 x ASUS GeForce 8800GT cards.

[/ QUOTE ] Back then 3D accelerators mostly just did texturing and filtering, so it was far easier to share the work load between two cards. All the Voodoo 2's did was each draw half the lines of a given frame and interleave the two together. Modern cards have to cope with performing vertex transformations, executing code on a per vertex or pixel basis, and many other complex tasks that makes sharing the load between cards far more difficult.

Chav Posted February 26, 2008 Report Share Posted February 26, 2008 Same principles though thorburn... in theory it's straightforward to share the bandwidth for multi-card, 1-display output... for dx 9/10 recommended batch size is 1000 vertices etc. typically problems are due to heat/power but with latest stuff there maybe (and usually are) driver bugs - as SLI uses lots of different algorithms to share the load (sharing GPU, sharing framebuffer, sharing textures etc) modern nvidia SLI is similar to RAID0 with harddisks....textures are typically uploaded to both cards etc (depending on config).... as scene generation evolves, SLI algorithms can adapt more dynamically at runtime- so a variety of algorithms are used, which can change on a per-frame/per-vertex-batch basis. usually opengl is more stable at driver level....
