Graphics stuttering issue related to netspeed (video inside)
I've been suffering from stuttering graphics when playing online in UT ever since I upgraded my PC and can't find a solution.
It looks and feels a lot like what happens if you play with an uncapped high frame rate (like 300FPS+) but this issue is happening even though I'm using a frame rate limit and/or VSync. It's almost certainly related to netspeed or UT's netcode because it's fine on some servers (like UK Insta which I think is a Windows server) but not on others (like my own BunnyTrack.net which is Linux). It's also 100% not a problem if I play offline. My normal setup: • Windows 7 64-bit • GTX 1080 • 165Hz monitor • VSync disabled and GSync enabled • Running D3D10 renderer with a 180 FPS cap If I uncap the FPS I reach 800+ FPS and the game goes insane. I have tried: • Different renderers: D3D10, D3D9, D3D, OpenGL • Different frame rate caps (100, 150, 180, 200 etc.) • Different netspeeds (lower netspeeds like 5000 do reduce the stuttering but make me unable to connect to Nexgen/ACE/etc.) • Disabling/Enabling VSync/GSync/ULMB etc. I've even tried changing my Linux server settings but this didn't help, and other people don't seem to experience the problem. Video: Any ideas? |
you can also trying adding your cpu speed into your ut shortcut(right click it and click properties), so it would look something like this
C:\UnrealTournament\System\UnrealTournament.exe -cpuspeed=NUMBER to find the exact number you can download a program called cpu-z or core temp and it will tell you. so for example under control panel mine is set to 3.2ghz, but with the programs mentioned the exact number is 3231 -cpuspeed=3231 The future is ACE NewNet XCEngine |
Thank you but it didn't help. I'm sure it must be network related because it's fine offline and some servers work fine.

Stop your firewall and antivirus for a test.
If it's ok Make an exception for UT in the two. This is for all server online or just yours linux one ? |
It's all online servers, although it is much better if ACE is installed. Probably because ACE limits the client's framerate to a reasonable level.
ACE doesn't completely remove the stuttering, but it makes it playable. I'm convinced that this problem is related to high frame rates, even if the user has set a frame rate limit in their graphics preferences. The problem seems to only be visible to players with a computer powerful enough to produce crazy frame rates (1000 FPS) when FPS is uncapped. |
I have absolutly the same shit stuttering.
And i have tried all settings, renders, fixes and so on.. Nothing help for 100% As I have noticed, this stuttering caused by UTPure, so at servers without it I can play smooth with my 150 fps. For example newnet servers have built-in UTPure and it works fine and you can play with any fps there. Try to use 80 fpslimit, this is the best value for servers with UTPure (when you set netspeed to 5000 you will have around 78 fpslimit, thats why it helped you). So, there is only 3 options: 1. play with 80 fps 2. use newnet 3. try to find UTPure developer and ask him to fix it. |
Have you tried running your framerate at 60?
|
check if you have this problem in singleplayer mode also.

I've replied a few days ago in the first topic you made on our site as well.
1 thing is really valuable of knowledge, to rule out the causes: Do you run your UT99 at 1 core, or at multiple cores ? It explicitly needs to run at 1 core. I don't read in your post, that you actually checked this. Might be very handy, to still do that! ACE can have problems capping your framerate if its running at multiple cores. Such things are really important to rule out before changing server settings or even starting thinking about other things. Minimize the game CTRL+SHIFT+ESC for taskmgr. Check processes tab Right-click unrealtournament.exe Go to details Right-click again Set Affinity Uncheck all cores. Only keep CPU(0) checked. *note in WIN7 and WIN8 8.1 this option won't be remembered by Windows, after you restart the process Thats why i've included the multicorefix executable in our ClassicUT99 version. Can you give an answer on these questions? Not replying, won't narrow down the rootcause. :) |
Sorry for the long delay, but I've replied on your forum:

Pretty sure UT just doesn't like running past 60 FPS.
|
i had it also once and took me over a month to find it,even i had some argue with my ISP about it and the problem was in a place you never beleive:i changed the mouse that was make the stuttering to be present.
this is just my 2 cents,maybe will help and just try it. |
The issue was solved by installing NewNet on the server. So it was indeed related to UT's old netcode as I suspected.
Unfortuntately NewNet was not suitable for my server because it messed up various things in BunnyTrack maps, but it may be suitable for other servers. |

I think you don't read your forum. I ave post for BT Newnet. |
