Visible stutter with small fps drop

Post by Clyongar » 27 Nov 2020, 17:09

Hello!
I'm going crazy, I can't solve this problem. I have tried everything.
As I wrote on the title, small fps drop 1-2-3-4-5 cause visible stutter in all games.
I also tried formatting, but nothing.

I discovered earlier, that if I lock the fps to 58, there are no drops. Above 60, yes.

PC: MSI B450-A PRO MAX, Ryzen 3600, RTX 3080, adata core reactor 850w, 16GB ddr4 3200 c16, 1tb nvme, 2tb hdd
Monitor: AOC 24g2u 144hz

Try this combo for stutter-quality-priority:

Monitor Menus: FreeSync ON or G-SYNC ON or VRR ON
NVIDIA Control Panel: G-SYNC ON + VSYNC ON
In-Game Menus: VSYNC OFF
Frame Rate Cap: 141 fps*
Multimonitor: Disabled or AOC as primary with game in Full Screen Exclusive (FSE)

Yes, you read correctly. G-SYNC + VSYNC ON in the NVIDIA Control Panel, but using VSYNC OFF with the in-game menu. The diametrically opposing setting usually produces least stutters in several game engines. Also, different-Hz multimonitor adds stutter if you use multiple monitors. Do not use windowed, do not use borderless, it WILL stutter with multimonitor!

See G-SYNC 101 for more advanced information (read all 15 pages), but this post is your TL;DR. Enjoy!

141fps cap will usually be smoother if you use RTSS as the frame rate cap, instead of in-game cap. However, in-game cap is lower lag and will usually be okay for VRR/FreeSync/G-SYNC capping.

Capping FAQ Warning: 3fps-below is only for VRR
VRR / FreeSync / G-SYNC: Approximately 3fps below Hz
Low-Lag VSYNC ON: ~0.01fps below Hz
RTSS Scanline Sync: No cap needed
VSYNC OFF: Use cap far beyond Hz

thanks for the answer!
I already read gsync 101 and tried all settings.

My settings right now:
Monitor menu: Freesync
NCP: Gsync on fullscreen - vsync on - low latency on
In-game: Vsync off
Frame rate cap wirh rtss: 141

from what I saw with afterburner log, I have frametime spike that cause frame drop and stutter

This is likely asset-loading stutter, game-engine-inefficiency stutter, and/or background processing stutter -- none fixable by VRR. But stutters at a low frame rate just above 60fps in ALL your games, seems to indicate a blanket issue if you have zero games that run smooth above 60fps.

I have questions, you need to describe your system:

Are you using single-monitor? (Secondary monitors disabled)
Are you using full screen exclusive? (Not Borderless, not FSO).
Which CPU?
How much RAM?
Are you using SSD?
Which brand SSD?

Also try to temporarily disable your system tray software, all RGB animator software, all cloud sync, printer utilities, etc. Startup without them temporarily. See what happens when you launch with none of that.

Single monitor
Fullscreen, but I tried to force exclusive on steam with "-window-mode exclusive" but I don't know if it work for all games. I'm sure it work for cuphead, because without that command gsync if off on cuphead.
PC: MSI B450-A PRO MAX, Ryzen 3600, RTX 3080, Adata core reactor 850w, 16GB ddr4 3200 c16, 1tb nvme sabrent, 2tb hdd
I tried to play on nvme, same spikes.

I did some test on different games, with and without exclusive command on steam. https://imgur.com/a/LPzT8sY
Like I said, the only one I'm sure it work in exclusive, is cuphead. Epsxe crazy spikes, I don't know why, maybe because it work at 50 fps.

this guy solved the same issue after unplug usb frontal on case, I can try, at this point I don't know what to do :roll:
update: ok I tried, didn't help
Also try to temporarily disable your system tray software, all RGB animator software, all cloud sync, printer utilities, etc. Startup without them temporarily. See what happens when you launch with none of that.
I did, I really tried everything

tomorrow I will mount my new lg cx, maybe the cpu does bottleneck in fhd. but I don't think, because I have spikes in all games, even in lite game like cuphead. if I change from max to minimum settings on paladins, still spikes. even on epsxe :x

update: this is what I get from latencymon after some gaming https://imgur.com/a/1skn668
update2: same drop and spikes in uhd with lg cx
update3: latencymon after 4k gaming https://imgur.com/a/iDccKDQ

Did you ever resolve this problem?

I have exactly the same issue. Once my FPS drops below cap, I get visible stuttering. Running all settings mentioned in the sync 101 guide. Even did a complete fresh reinstall of win10 with all drivers etc. Same thing. Everything is butter smooth at 140 fps but when it drops below 140 (130 for example) it becomes stuttery. Not very bad stutter but just not smooth anymore.

Still waiting for someone to address this. I'm also having this same issue.
