Started getting a stutter/lag when playing (but not editing) in the editor - graphics freeze for a couple of seconds but sounds seem to go as normal. It seems to occur when looking in specific directions. There seem to be a lot of people experiencing a similar problem but no fix! I’ve tried capping frame rates at 30 and 60 but stuttering still occurs. The stutter weirdly doesn’t always happen when fraps recording is on and when it does happen it doesn’t seem to appear in the recording… this video is smooth but when I was recording on the platform looking out to sea it was stuttering every few seconds! https://www…com/watch?v=8oTWZ-fOwdU&feature=youtu.be
- What programs do you have running aside from the editor? The editor is a performance intensive program so if you have a lot of other programs running it could easily cause lag.
- How large is the project you are working in?
- Are you using a significant amount of particles or materials that need shader compiling?
- Can you tell me what your average FPS is in the editor when you see the stuttering occur? You can do this by opening the console command and typing ‘Stat FPS’, then press enter.
- Can you post a copy of your dxdiag here so I can take a look?
- Does this occur in a clean, blank project with no additional content?
Hi , thanks for answering
1 - Nothing else intensive running, just chrome and antivirus really. I can run much larger projects than my own without the problem occurring. The LandscapeMountains map (with the hang glider) runs at a constant 65-70
2 - The project isn’t much larger than what can be seen in the video I linked.
3 - Not a significant amount of particles or materials - eight particle emitters and not a lot of heavy duty material in the scene. I got rid of the emitters and the problem persists.
4 - Framerate is mostly between 115 and 120 and it isn’t affected when the stutter occurs.
5 - link text
6 - I just ran a blank and clean first person project and they were fine, 120 fps.
However, I just ran the Example Project Welcome level and the problem occurs, it’s actually more severe in this smaller map. FPS stays around 100. As soon as I start fraps and play the level again the stuttering does not occur! When I close fraps it happens again, immediately. The stuttering occurs when looking towards the large Unreal “U” symbol and not away from it. When I delete the UE4_Logo static mesh the stuttering does not occur.
If I mouse through to a stutter point and stop moving the image will remain static until I move again. I’ve tried capturing the problem with fraps a number of times but the stuttering usually does not occur when fraps is recording and does not appear in the recordings anyway - maybe this is significant?
Do you have a set of reproduction steps I can take on my end? Unfortunately as of yet I have not seen any stuttering in any of the projects I have been working with. If not, do you have a project I can take a look at so I can see this occurring?
I’m not sure how it might be reproducible to be honest - I could upload the map somewhere if you want to take a look at it? It’s about 5gb. Just discovered that I can run stutter free by launching as a stand alone game, so there’s no rush! Thanks for taking the time to help. What would be the best way to do a clean reinstall?
If you are able to upload the project to a trusted FTP service such as google drive and share the link (here or send me a PM on the forums) I would be happy to take a look and see what may be occurring.
Unfortunately, I am not seeing any stutter on my end when I look at the ocean or perform any movement actions. Is there anything else I can try to reproduce this on my end?
We have not heard from you in several days. I am marking this as answered for tracking purposes. If you are still experiencing this error, please comment with the requested information.
Hi - I had left it for a while due to college work, installed new AMD drivers today and the stutter seems to have stopped. Thanks for your help and patience, hopefully this is the end of it!
Im having problem with my editor, I created a clean slate project but when I started moving the camera the movement was so laggy, and when I enable the FPS it shows my FPS quickly drops from green to red and it just goes up and down quickly. I tried lowering resolution but the result was still the same. I’m no longer motivated to practice game dev because of this. please help me resolve this. this is my pc information.
