    Thanks all, I appreciate everyone's attention and efforts on this.

    I have reported the bug FWIW, we'll see what happens and how long it takes to find out what the real deal is. Reproduce-able bug, driver issue, something else, or my machine is a delicate rare flower that just doesn't like 4.19.

    FYI the video I made and sent to Epic, if you want to see what I am seeing FWIW.

      After seeing your video, I entered the project again and waited, waited, and the hiccups started to appear. The gap from the FPS at the hiccups increased and I found another thing interesting: while the editor is open (not running or simulating) if you click outside the editor in a way for it to lose the window focus (ie: you can click on Windows' Toolbar in the bottom) and then click in the editor again, you will see that the FPS presents a large difference from what it was before. To see the regular FPS back, the only way is to run or simulate. Im rolling back the driver just as an experiment.

      PS: I have rolled back 5 versions back and the issue still there, so one can really reproduce it. As soon you get the issue number, let us know, so we can vote on it for fix priority

          FYI - I tried it in 4.19.1 and the same problem exists. Does not seem to be addressed yet.

            Yes, the majority intent on the .1 release is to address crashes.

              How much RAM do you have ? I had the same issue until I upgraded to 16Gb of RAM.

                  For the record, me:
                  24GB system, 980GTX 4GB GPU, i7-4790K @4.00Ghz+ 4 cores/ 8 threads

                  You have a nice machine Nilson!

                  I have not tried re-updating to 391.35 yet, not sure it will make a difference with 4.19.1

                    My Blueprint Compile times have also gone up, along with the Editor hangups. It seems worse in 4.19.1 somehow. But all of this is worse than 4.18. I know the BP Compile time issues are from the Compilation Manager.

                    Even hitting Play for PIE is gross

                      I'm glad others are able to somewhat verify my issues, but of course it saddens me that these issues exist for them. Victor and others are having a tougher time than me, getting rid of the two particles made my situation acceptable. Although I still get a crappier performance and occasional screen hangs that were not there in 4.18 and PIE.

                            I am getting similar hanging / hitching specially when using any stat commands, including 'stat startfile', 'stat gpu', 'stat rendering' to name a few. I am running 4.19.1, and have a GTX960 with latest drivers. Happens in a blank project as well. Does not happen in 4.17.2.

                              Same card here, GTX960. Same issues. Going back to 4.16.3.

                                I see than I am not the only one with simillar issue. I have GTX 1080 with latest nvidia driver. The problem must be somwhere in drivers <-> UE. I got a simple scene with some BP meshes on the scene. After a while I got some laggs every half a second or so. The strange thing is that when I press G to hide all the lines etc. everything is normal (120 FPS constant), but just when I press G to get out of Game View it starts to lagging.
                                The exactly same scene in 4.18 is working like a charm.

                                Our BP have some Billboards attached with simple material and texture. After I hide this is helps a lot but not 100%.
