I think it's because Fermi cards downclocked core and memory way too low at idle state and Maxwell uses much higher idle values:
If you moved the cursor with Fermi at idle power state and PCIE mode 1 vs highest power state (p3? p4?) and PCIE mode 3.0, there was a huge difference in how the cursor moved. Doing the same thing with Maxwell, you still notice a difference, but it's much less than before. I was really worried that the "Gigabyte Flex Technology", which is their custom implementation of having a crap ton of display outputs would cause some major problem, but it's pretty much flawless. There's no lag or buffering or anything like that due to it. I'm on the 2nd revision Gigabyte 970 though, I did hear about people on the Gigabyte 970 G1 first gen with backplate having problems with ports flat out not working at all.
The 970 card uses line based interrupt mode by default, not MSI. If I forced my Fermi card from line based to MSI mode, there was a small difference in cursor movement, but nothing that huge. Generally it felt worse in MSI mode though. When I do the same thing with the 970 card, there's not a small difference, it's a large difference, and it makes cursor movement much worse. There must be some reason Nvidia doesn't use MSI mode.
The reason I was testing MSI mode in the first place is I was going to see if using the 970 in MSI mode along with a PCI-E sound card in MSI mode would fix the PCI-E sound card's latency problems. For some reason, the problem is much less pronounced with the Maxwell GPU than Fermi and you can actually run a PCI-E sound card with this GPU.
So why would nvidia will be using MSI on laptop with the same card ? it's obviously same 970 chip just cut with some cuda core and 192 bit. AMD used MSI on both Desktop and Laptop cards. I can't understand why Nvidia doesn't have MSI mode enabled for all of their cards. at least why on Laptop it is MSI and not on Desktop ?

We are looking for the common things, better than trying to find rarity and to pinpoint any thing that repeating in sustain of performance or numbers, sometimes feelings gets you going, or you don't believe in love ?Edited by x7007 - 2/20/16 at 5:03pm
