So I set my pre-rendered frames to 4, no change for me, except input lag, very noticeable, so i'm back to the default value.
@Bitmaster: unfortunately, I don't have a second PC or a PCIe USB card to test this. I think i test all things available, motherboard bios update, clean reinstall of Nvidia driver with DDU, all my USB ports, change the poll rate of my mouse, change the CPU priority for TIR driver, pray God a dozen of time...I think i'm done with this issue.It start when the move to 1.5 was done, it was perfect before, and i have absolutely 0 issue in my others sims. In the next few weeks, I plan to upgrade with the new Coffee Lake generation, I will see...
