So I recently swapped out my 1070 for an Aorus 1080 TI Xtreme and I'm noticing lots of stuttering that wasn't there before. Decided to do a fresh Windows install (as well as upgrading from a 550W to a 650W PSU and an M.2 drive for the OS) and I'm still seeing frame-time stuttering in almost all games. First off, the rest of my system; * 6600k @ 4.5GHz (stable) * ASROCK Z170 GAMING K4 * 4x 4GB Corsair Vengeance LPX * 480GB SanDisk SSD PLUS * 2TB TOSHIBA 7200 HDD * Dell S2417DG G-Sync monitor (all games running at 1440p native) * 650W EVGA GQ Series, 80 PLUS Gold PSU * Latest Win10 update Things I've tried; * Latest NVidia drivers/rolling back drivers (DDU) (currently on 385.69) * Disabling Steam/Origin overlays * Remove CPU OC & RAM XMP profile * Disable HPET * Various combinations of VSync/Fastsync/FPS capping (currently just have VSync enabled in NVidia settings, disabled in-game) * Fullscreen/Windowed * Changing display response time (Normal/Fast), overclocking display (144Hz/165Hz) - can't hurt to try * A few other things which I've subsequently forgotten (I knew I should've made a checklist!) NVidia settings are all at default, except: * Maximum Pre-Rendered Frames: 1 * Prefer Max Performance * V-Sync enabled * G-Sync on Windowed and Fullscreen GFX card is clocked at "Game Mode" (1721/11232) using Aorus Graphics Engine (NOT running in Sys Tray). Results: GTA V (all max except advanced settings, SSD) https://imgur.com/a/TpXMK Witcher 3 (max settings, hairworks off, HDD) https://imgur.com/a/HqSPB Doom (all max, HDD) https://imgur.com/a/qsRId Battlefield 1: Conquest (all max, DX11, SSD) https://imgur.com/a/tpj0J CoD: WWII (all max, SSD) https://imgur.com/a/G54EQ Nex Machina (all max, HDD) https://imgur.com/a/dytrg Now, you might look at a couple of these and think they're not too bad, but bear in mind these are all best case scenarios. There are other benches I've performed where FPS drop below 60fps (sometimes sub 30fps in the case of BF1) depending on what's going on on-screen. Witcher 3 for example, I could pan the camera around (with a control pad for accuracy) and not see stuttering on my old 1070. Sure, the overall FPS was lower, but it didn't stutter like it does now. ...and as a quick test, Battlefield 1 running at Medium settings; https://imgur.com/a/cOWyY (again this was the best of the bunch, but sub 60FPS on medium doesn't seem right) I've been out of the PC game for a while; are there any other tests I could perform? Any help or advice greatly appreciated. I seem to be spending more time fiddling and less time actually playing :-( I should add that my 1070 was running with pre-Creators update.
