So I can’t get any smooth movement/animation/rotation in UE4.25.3 on Mac OSX 10.14.6 Mojave,
30" inch screen, 2540 x 1620 resolution, tested with two different graphics cards
( NVIDIA GTX680 4GB and AMD Radeon Sapphire Pulse 8GB) and
this is a MacPro 12-core (2x2,4 Ghz 6-Core Intel Xeon) 32GB 1333 Mhz-DDR3
No matter if we talk about camera movement, player movement, rotation on an object or whatever.
No matter which project, which demo projects or even the smallest tests.
I always see a small “stuttering”, no smooth movement.
I really noticed this when I double checked with other engines.
hen it became very obvious and since then drives me nuts.
Example: For testing I started an empty scene, removed everything, just put a cube in there
nd rotate it (with a delta seconds multiplier) frame rate is at 100FPS and
I STILL get no visually smooth movement.
I resized the editor to 1/4th on my screen, still the same. Tried r.screenPercentage 50, still the same.
(The Epic Demos “VehicleGame” “ShooterGame” & “ActionRPG” run on good frame rates
ere as well (around 45-50 on my system in fullscreen)
but I have the same stuttering when moving or rotating the player/camera)
I tried whatever I could find about frame stuttering (r.Vsync 0/1, switched between
forward/deferred rendering, enabled fast math for metal, etc)
I don’t know what could be causing this and this really drives me completely nuts
because this does NOT happen at all with Armory3D/Blender, Godot, Unity or Away3D. Even with heavier scenes.
(My suspicion is that this might have to do with Unreal using ShaderModel5 and
I am pretty sure the other ones do not? Any thoughts on that?)
BTW: I also get Screen Tearing on camera rotation. Often very noticeable.
his happens in Unity as well, even way more extreme than in Unreal.
ut then again, does not happen with the others…)
Any ideas what else I could try?
Thanks & best,
