Issue with sawtooth/pixelated/jagged/lumpy stroke?

I've also noticed that when I used edit stroke it was set to centered not outside and it didn't look as good when I set it to centered. I tried setting my layer style and layer stroke to centered and both were jagged but looked slightly better when the position was set to inside. though, then the inside had a bit of pixelation. I just want all the strokes to look nice again set to outside position.

First off, thank you so much for responding! I really appreciate it. I saved it as a high quality jpg and provided what happened in the first two image attachments. It still shows the same as in photoshop.

this is what my cache levels look like? I'm still kind of new to the more technical issues so I'm not sure if this looks correct at all or not?

Which leads me to stroking from the edit menu THIS ACTUALLY WORKS FINE! The edit menu stroke is not pixelated. So while that works and looks fine, I still would like to know why the regular stroke no longer works when it used to just fine? It doesn't matter if I double click the layer and stroke or if I go to layer style and stroke...Those two do not work for ANY TOOL not just the brush tool to answer your question as well. All tools to make a circle with are suddenly having the jagged looking stroke issue. So why is only the edit menu stroke working but not the others? Here is a picture of the edit menu stroke looking smooth and perfect and not upsetting lol :

and then to answer you question again the mode for the layer style and double click on the layer and stroke are both set to normal for the blending mode and still have the jagged looking stroke:

Save the stroked image as a high quality JPG, and view it in another application, like Windows Photo Viewer.   This will address GPU issues making the stroke _look_ jagged when it might not be.

Check Cache levels in Preferences > Performance.  It  needs to be set  to a value higher than 1.   (This is related to my first sentence.)

You are stroking from the Edit menu?  I doubt this would  have survived a reinstall including  using the Cleaning tool, but check the blend mode in the Stroke dialog.  I was thinking 'Dissolve', but actually, the result would be way worse than you are describing (as below).

This only  happens when you use Stroke, or  when you use the brush tool  directly?

OK I have looked  through your screen shots again, and I see you are stroking with a Layer Style.  Not much to go wrong there, but make sure that the blend mode is set to normal.  Blend modes work differently with strokes in Layer styles, so I don't think this is the issue.

Right now I think we need to eliminate GPU issues and cache levels, and  take it from there.
