Ok so this is killing me. For the past few days, I've noticed that while playing any games, my video and sound will studder for a sec or two causing the game to pause. I've done a complete uninstall of the latest drivers as well as a clean install of the video drivers using DDU. Not sure what changed since nothing new has been added. Any help would be great. Tks ... Specs below: GeForce GTX 1080 Ti (2x) - SLI | Winblows 10 Pro (1709) | 32GB RAM | Game on SSD Drive
Ok, you'll have to tell us more. You say it's only been happening recently, so you never had the issue before. Has there been any HW or SW changes? Does it happen in all games? How about YouTube/Netflix/General Video Streaming? Tell us more, otherwise it's hard to diagnose.
Check your IRQs. I had an issue like this on an Asus Rampage III mobo where the Intel SATA controller shared an IRQ with PCIe 0. (aka primary slot for GPU) I had to manually change the IRQ in Windows for the SATA controller to fix. It could also be another device. I've seen FPS latency caused by a wired mouse.
Try running on single GPU, check temperatures, check available free RAM when lag occurs, update to latest BIOS and drivers, have fun.
people are still under the misconception that shared irq's cause stuttering huh.... pci-e doesn't even have a physical irq route, they are MSI native with the software layer simulating IRQ's.
Problem with shared IRQs is at the drivers level. Drivers of all devices with the same IRQ are notified about interrupt from device, and they should check whether it is their device (may be even make a call back to device) to dispatch DPC call. That additional check can increase ISR time. You spotted main problem with MSI mode - it is native mode for PCI-E but still many devices with their drivers utilize legacy simulated interrupt mode.
Simulated IRQ's don't queue in the way physical do though, Stuttering on recent boards are at the Process interrupt level, not the physical (unless you have an AMT enabled intel nic) Also the IRQ table for that Rampage board is set up so ICH10 AHCI/SATA is on irq 20, PCI-E 16x1 is irq 24, so im not sure they are thinking of the right board anyway,
Thanks for all the replies - even the English major correcting me (btw I did that purposely) | So my system is water cooled running an ASUS Maximum VIII. All drivers and BIOS are up to date. Today I'll disable SLI and see if that resolves any issues. Before coming on here I just ran through a couple of YT vids and noticed on one of them the "S" (we'll call it - Don't want the grammar police after me). I'll keep you up to date. Tks
Just a Hail Mary, but turn off ingame vsync, turn on nvidia panel vsync and set FPS to 2-3 FPS less than monitor refresh rate.
Sometimes windows can get bogged down so to speak. All the extra programs we run. Sometimes its nice to just have a separate install of Windows just for games. Like the insider preview works really good! SLI is the 1st place I would look
