Title: Display Stutter...
Post by: uberslug on November 04, 2017, 10:18:50 PM
I am experiencing some freezing, jumpiness, or stutter during simulation.

I have an i7-6700K with 32 GB of ram running at 4.00 Ghz, a relatively fast SSD, a GeForce GTX 1070 running at 2560 x 1440, and a 550 watt power supply. As you can see in this screen shot I have the frame monitor running and it shows 166 frames per second [the MSI and GeForce monitors show the values in a range from 140 to 165 fps but are not captured in the screen shot].

(https://s1.postimg.org/4mayqk5rl7/core_2017-11-04_17-18-49-247.png) (https://postimg.org/image/4mayqk5rl7/)

At times it looks as though the display leaps past a bunch of frames when going underneath banners, past braking markers, or over curbs. It is also evident on the exit of some slow corners on Motegi. It seems to go away after a reboot and then reappears after opening Chrome and / or Solid Edge. CPU utilization seems reasonable at approximately 80 percent of one thread, GPU utilization bounces between 60 and 80 percent, and GPU power runs at about 50 percent.

Anyone have any ideas as to what is wrong.

you're using other software to enhance the game ? like Reshade ?
do you have a custom profile in your graphics card ? you messed with some settings ? you have the latest display driver ?
what are your game graphics settings ?
you have the same problem with stock moto and victoria map ? (without the plugin?)
you must use LAA  for new big maps https://www.techpowerup.com/forums/threads/large-address-aware.112556/

I had this happen to me with a Windows update

It was how windows was managing memory, sorry but cant remember of my head what I did but I will try to look back into it.

I solved it by the old google serch lol will see if I can find the old links

Try running other games and do some tests

run a monitor for memory if you can

Drink more Jack Daniels lol

Do NOT hit PC with a hammer!!!

maybe its not the ingame graphics setttings but the windows graphic cards setting. Do you use default or other settings?

So, after 10 or so hours of futzing with settings, drivers, and reading everything I could find on the internet, I think I have determined that I am just plain #*%&@$!

Actually, it's not all that bad.

I tried a number of gee whiz settings and they either did nothing or made matters worse. The micro stuttering got to the point where I could have sworn there was someone spinning a propeller in front of my eyes whilst I attempted to ride around. The stuttering increased in frequency the longer I rode around until it was nearly constant. The largest lapses were entering and exiting slow corners but they [the stutters] would be everywhere [made it difficult to hit braking / turning points].

I eventually read about how the latest NVidia drivers are not playing well with the latest Windows 10 Update. The drivers for my GeForce GTX1070 were updated just before the latest Windows 10 update and then everything went to *%()#. I thought I would try to go back to the drivers from MSI which are from much earlier in the year.

I removed the latest NVidia drivers, rebooted, and Windows somehow magically reinstalled the NVidia 388.00 drivers without the associated NVidia Experience drivers / applications.

Low and behold, it is 99.99 percent stutter free and running at anywhere between 135 to 165 FPS.

I will do some more testing in the coming days to see if the performance holds or if it gets better / worse.

I had same problem mounth ago, i was due to MaxHud plugin, i resolve it by turning off all HUD and then re-turn it on.

Err, that would be very strange man.

I have sometimes stuttering when FPS drop below synchronised number.

What's a "synchronised number" ?
What hw are you using (CPU, GPU) ?

Theoretically it is possible for the plugin to slow things down a bit, but to be honest it should be totally unnoticeable unless your hw is barely capable to run GPB.

And the fact that switching the plugin widgets OFF and then ON solved the issue would tend to indicated that there's a problem somewhere else.

Max > yes very strange (it may be a coincidence also but if i remember i did i 2 times), since that i don't have the problem anymore but had another one, randomly some hud shows and some not, and the only way i can re turn it on is by changing the HUD scale !

@HornetMaX when I play on 75 fps with V sync on then on some parts of the tracks like Catalunya when FPS drop to 70 or lower then the screen starts to stutter like there was much less than 30 fps. I do not use nVidia adaptive sync just fixed on 60 or 75 fps.

Very weird. I'll have a look (when I can, PC is down at the moment).

Vsync is a bad idea anyway. If you have gsync or freesync, use that. If not, then just don't use vsync.
Not sure your problem will go away, but vsync is generally considered bad for games that need a "solid connection between inputs and display refresh".

I understand. So I will try nvidia sync. Thank you for information :-)

So I removed NVidia Driver Version 3.88.00 and installed MSI Driver Version 3.79.06 and my stuttering issue seems to be resolved.

The only downside is a drop in NovaBench GPU Score from 992 - 161 FPS - 7158 GFlops to 803 - 117 FPS - 5784 GFlops.

GP-Bikes performance seems to not be affected at all so I think I am good to go.

3.88.00 is not the newest, I have 3.88.13 which came out quick to fix issues with the one you had so maybe give it a try?

I will give 3.88.13 a shot.

It may have been my imagination last evening, but, I noticed the stuttering when I had the Connection Speed set to 'Very High' instead of just 'High'. It was the only change I made to the Settings after the previous evening's travails. After a few laps of increasing frequency of stutters I changed it back and the stuttering went away.

I think that setting should only be relevant when playing online. Do you have stuttering testing (offline) ?

I was having the stuttering issue both on and off line when the connection speed was set to very high. I set it to high during my troubleshooting in an attempt to normalize the settings. I was not adhering to the 'only change one thing at a time' axiom at the time so I have no evidence whether or not the stuttering issue has a causative or correlative relationship with the connection speed setting.

I may do some actual testing this weekend to see if I can replicate the issue.

I installed v3.88.13. The micro stuttering came back although it was not nearly as bad as it was with v3.88.00.

I have since reinstalled v3.76.09 as it seems to work better with GP-Bikes. Overall NovaBench results are down but I can live with that.
