Gotcha.
Makes sense on the flash, and with no onboard that would make a little sense, not so much of there are multiple cards.
I'd shoot an email.
Maybe try it without SLI before you do?
Wish I could have been more help. Best of luck
Resolume only uses one card for processing. Having the second in x8 shouldn't matter at all. It's just an expensive way to share textures from your main card. Did the resolume guys say that was an issue?Frischvergiftung wrote:next day we're still troubleshooting. but two things we already learned are:
1) our two graphics cards didn't run on 16 pcie lanes each. one of them only used 8 lanes, because the guy who built the machine stuck one of the m2 cards in a slot that it had to share with the graphics card. removed that m2 card, so thats better now. both cards at 16 lanes now.
2) our 6 x 1 grid texture at 11520 x 1200 px will run nowhere as smooth as a file with the same amount of pixels but using a 2 x 3 grid at 3840 x 3600 px. the latter will perform better.
still puzzling...
Underneath the hood, GPUs really like working with powers of 2. It's a math thing.2) our 6 x 1 grid texture at 11520 x 1200 px will run nowhere as smooth as a file with the same amount of pixels but using a 2 x 3 grid at 3840 x 3600 px. the latter will perform better.
The texture still has to travel via the mobo to the second GPU. Using a faster PCIe lane for this, does impact performance. Granted this impact depends on many factors, and it is very likely not the reason for the bottleneck or stuttering OP is experiencing. But to say it shouldn't matter at all is taking a very steep turn through the curve.Resolume only uses one card for processing. Having the second in x8 shouldn't matter at all.
