High GPU usage on Ryzen 4700U #212

Hi,

I just started using Goxel and I find it very awesome, great works btw ! I have a HP envy x360 with an AMD ryzen 4700u. There is only on problem I've, My laptop get pretty damn hot in few seconds, my GPU usage is about 95-100% with an empty scene in edit mode.

I don't know if it's normal or not. The app still works fine for the time i've used it, but my fan is running like hell

I don't want to compare to magicalVoxel, because I don't think they are similar, but my GPU don't get higher than 10-15% in edit mode with it.

(Sorry for my bad english) cpuHighUsage

Thanks for the report. This could be because the FPS of the application is not properly limited. There was a bug report of this a while ago on Windows but I couldn't reproduce it myself. I guess I should put the FPS somewhere in the UI.

Thank for the answer. I try to limit the fps with AMD Radeon software.. Sadly, I don't think it works, there is no improvement on the GPU usage.

That happens not only with GPU, but with pc's CPU only too. I installed goxel from apt repo in XUbuntu and my pc doesn't have a dedicated GPU, only the integrated one.

So, the first thing that I notice was the high use of processing, the top command indicates like 300% of processing (for my a i3 6100).

Like I have some experiencing in making engines, I looked at the main function where the loop_function is called. And, there is no one wait function for it, then is this the trouble with high processing.

Using the function usleep(33000) from unistd.h, after the line glfwPollEvents(); at the loop_function, the problem is solved, but the editor stays a little slow to update the voxel position (it just notable by who saw the running before).

NOTE: the desktop loop_function should have some waiting, but the emscripten code no. I remember the emscripten gives hints to not uses sleeps functions or any other delay function for main loops.

This happens because of rendering it without any cap, which means it will render as many frames as possible, I Implemented frame cap in one of my software in c++ which reduced the cpu usage and gpu usage significantly, I'll try to port it to c.
