I have updated the build (just download and reinstall it). The new version allows you to move in the VR mode (using Oculus Touch or Remote)
This programm should allways start in paused
I do not think this makes sense, because then you can not rotate the image, change the parameters, etc. If you have a weak video card, so probably then you should use Mandelbulber. It will work slower, but at least you can edit the fractal.
The idea of this program is that it would sharply raise the speed of rendering using parallel computations on the GPU. Modern video cards are hundreds of times more productive than the CPU. But if you do not have an appropriate video card ....
OK. I tried to make an adaptive setting. Now the program at the start checks the rendering time and, if it is less than 10 fps, reduces the window size. Three dimensions are available: 1920x1080(default), 1440x720 and 1024x512. I tested this algorithm on my oldest card (GTX 680) and, in the worst cases, the rendering speed was within 6-7 fps. It is not perfect but acceptable. On my system (GUI: AMD R9 Nano, Rendering: Titan V + Titan P) the FPS never falls below 30 fps (1920x1080).
One tip - use "Microsoft Basic Render Driver" as a GUI adapter (it's default now). Drawing the buttons can be performed on the CPU, it will at least slightly relieve the main video card.
