Hi, after using only notebooks for over a decade, I am thinking about getting a (Windows) desktop PC. Not being much of a gamer, my primary concern with performance is deep-zooming the Mandelbrot set in UF. Does anybody have a suggestion for this, or even a benchmark computed on their machine?

I've read Frederik suggesting an i7. Is UF specifically tailored to Intel? I never read anything abo

Ok, this might be a bit of a weird one, but I just managed to produce a problem that I've been meaning to reproduce for a while now:

Sometimes, when I and rendering something to disk while the preview is still also rendering, all UF windows start flickering erratically and the program becomes all but uncontrollable. In most cases I can somehow hunt down the window in question and close it or

I've been playing around with the animation feature lately and have been attempting some fairly simple Mandelbrot zooms at low magnification. I created an AVI file for a 15 second video (both 60fps and 30fps) at 3840x2160 resolution, but when I tried to load it up I get an error that the video file is unplayable due to possible corruption. I attempted to play the file under 4 different media play

Hi All,
I have uploaded a new version of SlopeMandNewton, this versione presents 10 sets, all compatible with the last one, now i can share also the parameters.

I was wondering, is there anything I regret about this fractal community that I've known for 20 years now?
Yes, there is something, I have lost several contacts due to different political views, I will start by saying that I don

With some of my recently changed formulas I've run into a problem. Here's a screenshot illustrating the problem:

The red bars should not be there. If I reload the fractal, the bars are different but still red. I also get different red bars with and without anti-aliasing, and different red bars when rendering. This image is with min and max threads of 20, the max on my system. With fewer

I've seen this several times now with different fractals, and I don't know what causes it, but sometimes multi-layer fractals are offset. This problem seems to go away when activating anti-aliasing in the working window. Here's a screenshot:

It seems to be always exactly 1 pixel along the y-axis of the monitor, no matter the rotation of the fractal. And it also remains 1 pixe

I am writing a coloring algo at the moment and I tried using min(val1, val2) where val1 and val2 are two floating point values, and the function does not exist (error: invalid function). So I went looking for an equivalent function and I cannot find one. Does UF not have such a fucntion? It seems like such a basic thing. Am I just overlooking something?

When changing parameters, the image only updates after you change it again, after which the image will show the image with the previous parameters.

For example, starting with a power 2 Mandelbrot, changing the power to 5 will not update the preview, and changing it to 10 will update the preview to the power 5 Mandelbrot. Changing the power to 15 will update it to a power 10 Mandelbrot.

Completely new to Ultrafractal.

Is it possible (and if so, in a simple way) to do black and white (no gradient) scatter plots for Julia sets with Mandelbrot parameters (i.e. constant offset) as input (ideally selecting from a Mandelbrot plot)?

And is it possible to adjust "dot size" for that in a reasonable way? Background: The goal is to have these printed, and pure dots on big resolutio

In the formula editor, if I open up a Replace Box with Ctrl-H and try to paste into one of the lines inside the box with Ctrl-V, the replacement text goes into the formula at the cursor position instead of into the Replace Box.

This is not the behavior that I had expected

I have an older INtel i7 computer I don't use anymore because I replaced it with newer one. I would like to use the old I7 computer as a server. To my understanding. THere is a way to make the older computer into a Server. Reading the instructions I am trying to understand some things.

Does having the server mean that all computation runs on the server all computers running server or is

I'm addicted with this new combination that i have discovered, here's another one, a different zoom of Newton Mask, i'm thinking to explore this formula and maybe create a new one exploring the Point of Source method in Slope 3D Enhanced III, it's the first time that i use this method in Slope and with Newton formula is perfect.
I will explore more
Ciao buon week-end

Request: Better control over periodicity checking.

Currently, periodicity checking is controlled by a limited set of options: "off, rough, normal, conservative". I don't know how it is implemented, but I am guessing some orbit distance threshold preset table or similarly.

I work with fractals that are very sensitive to the periodicity checking, yet turning it off altogether would real

Is it possible to display the colors of a gradient on a layer. just as they are displayed in the editor ?
Layer would be identical to gradient colors.

When I'm browsing formulas, it's very helpful that UF calculates and shows thumbnails of each possible formula.

There are also drop-down lists in many formulas, such as the built-in Function list (sin, sinh, asin, ...). It would be very helpful if UF could show calculate and show thumbnails of each choice.

Not easy to implement, but as long as I'm dreaming ...

Hi Frederik,

When using UF6 (and the previous versions also) my computers CPU (Intel I5 with 4 cores) is working at 100 % while my GPU (NVIDIA GeForce GTX670) is doing ... right ... nothing at all.
