Hello
I need high-resolution of a cloth effect, but impossible to subdivide more the cloth emitter because I have this screen info :
(I have a poweful pc, 128 GO ram, rtx 3090, and amd 3970x)
Try what is suggested in the “Max Simulation Points” slider description.
I haven’t seen the description in the slider 
Ok I tried but same result 
(the subtool is around 1.2 million)
Hi @MrCedric ,
The Dynamics feature is performance-intensive. It has to do complex calculations for every point on the mesh and simply cannot cope with point counts above a certain threshold.
It will be necessary to perform your simulation with a lower resolution mesh, and then subdivide it or use Dynamic Subdivision to smooth it. This is still capable of producing very fine wrinkles.
Good luck!
Thank you for your help, there is some hope 
But I don’t really understand the steps that you describe, how to lower resolution and having very fine wrinkles at the end
In fact I saw some tutorial about “Dynamic” and “cloth” (michael pavlovich…), but I’m stuck. I certainly miss something…
Read carefully what I highlighted in green in my first reply. Let me re-iterate. "Cloth simulation works best on low polygon meshes. You can use Dynamic Subdiv to show a high-resolution preview and then apply the subdivisions after you have the effect you want."
The Dynamic Subdiv it refers to is in “Tool > Geometry > Dynamic Subdiv”.
Sure, if you look my last screen capture you can see that the dynamic button is activate
Did you lower the polygon count on your mesh to below 1 million? You have to get the polygon count down first. Preferably to the default of 250000 of the Max Simulation Points for good performance. That, in combination with Dynamic Subdiv, will give you the result you are after. Again,"Cloth simulation works best on low polygon meshes. You can use Dynamic Subdiv to show a high-resolution preview and then apply the subdivisions after you have the effect you want."
Ok so I tried again.
To show the bad result I have I made a quick scene with the sphere and helix ready to use in the subpalette.
My sphere is at 500 000, and like you see with or without dynamics the result is quite the same, looks low-res, no nice flat mapping around the helix.
Where is my mistake ? 
nobody ?
ok so that’s impossible, I will do it with Blender or better Marvelous
