How to unload texture?(SOLVED)

Questions
1

I need to create a new texture every frame. What happens with previous textures? Looks like they don’t unload, because dmengine use more and more memory.

local header = {width = SCREEN.WIDTH, height = SCREEN.HEIGHT, type = resource.TEXTURE_TYPE_2D, format = resource.TEXTURE_FORMAT_RGB, num_mip_maps = 0}
resource.set_texture(self.resource_path, header, SCREEN.BUFFER)

Isn’t it garbage collecting after a while?

3

No, dmengine use 10gb memory.I have 12 gb. But dmengine can’t get more and freeze.

4

And what happens when you’re closing in on the mem cap of your desktop/laptop? Does it crash with oom or does it gc?

5

It can’t get more and freeze. Also my pc is freezing too, look like it try to free memory. Then if enought free memory, dmengine create one more texture

Same happened again=)

M.WIDTH = 960/2
M.HEIGHT = 540/2
M.BUFFER = buffer.create(M.WIDTH * M.HEIGHT, { {name=hash("rgb"), type=buffer.VALUE_TYPE_UINT8, count=3} } )

function M.update_texture(resource_path)
	local header = {width = M.WIDTH, height =M.HEIGHT, type = resource.TEXTURE_TYPE_2D, format = resource.TEXTURE_FORMAT_RGB, num_mip_maps = 0}
        --comment next line no memory leak
	resource.set_texture(resource_path, header, M.BUFFER)
end

1)Open project
2)Press 9 (it wil show memory usage in right top corner)
3)Memory usage will be increased, every frame

In native_render/helper.lua you can comment resource.set_texture

Memory usage isn’t increasing for me on OSX. You’re on Windows right?

Yes

Hmm, and you’re actually running out of memory eventually? It’s not just a number that is growing but has no real meaning?

16

Yes. I can play 3-4 minutes, then dmengine use 11gb of memory, and all freezed=)

Also i am not sure. But i think that on desktop i don’t have memory leak, it also windows. Now i use laptop. But i can’t check now.
