[0.13.13-0.13.15] High GPU usage

[axazol]

100% of GPU usage and low FPS when alot of tree on screen simultaneously (max zoom and/or in forest). Meantime if i run out on free space GPU usage lowers to 30% and FPS rises back to 60.
Actual only with [video-memory-usage=all]. No issue if use 5dim_automatization_0.13.1 or Yuoki_0.3.58 separately.

The frametime is (once again) lost in the flip which suggests an issue with v-sync or the driver. I lost track on the status of the v-sync debugging, but you cold try to enable it and/or switch from d3d to opengl and vice versa.
Please upload the log as well.

Actually further investigation shows that high flip times is not necessarily related to vsync. Render sends all the data to be rendered to the video card and the video card will start rendering. When we tell the video card to flip, it will sometimes have to wait for the framebuffer to actually finish drawing. So high flip times and high GPU usage means slow rendering.

Meantime if i run out on free space GPU usage lowers to 30% and FPS rises back to 60.

I don't exactly understand what you mean by "if i run out on free space" ?

If your video card can handle it(and yours should), you should set [video-memory-usage=all]. This means all textures will be in video memory and will render quickly, and you will have high FPS.
If you set video-memory-usage lower(for video cards that don't have enough VRAM), some textures will (sometimes) stay in system RAM, meaning it will be much slower to render them and you will have low FPS.

Can you tell me what FPS you get for each video-memory-usage setting? (make sure to test in the same savegame, in the same location, same zoom and same mods)

It's mean to the area with lower count of entities around (open water or desert)

If your video card can handle it(and yours should), you should set [video-memory-usage=all]. This means all textures will be in video memory and will render quickly, and you will have high FPS.

Yep, it should handle it. But at [video-memory-usage=all] i still have more than 60% VRAM free. I'll test it further..

Working on it...

Tried to test on fresh client - all the same. In all tests max VRAM usage <= 850Mb by game

Thanks for the tests.
The video memory usage is ok. Based on your atlas size the video memory usage should be 16384 * 12971 * 4 = 810MB so everything seems to be loaded correctly.

But your GPU usage very odd. Your GPU should handle much more.
I have tried similar experiments on my GTX 760 (which is less powerful than yours) and to reach 100% GPU usage, I had to draw much more sprites in 4 times bigger resolution, and even so, I still had 44FPS.

Are you sure you don't have anything affecting your GPU usage or rendering? Maybe you have some settings(like texture filtering) set in your nvidia control panel?

Can you send me the list of mods you used when doing the tests? A factorio log will contain the list of mods and other useful information.

This should be fixed in 0.13.16.
We have added option to enable mipmapping for tree sprites, which according to our measurements greatly reduces GPU load when rendering zoomed out forests.
