Problem with render texture

[Sly88]

hi guys,
I try to implement a mini-map system in my game. I have map 2048x2048 and I use render texture to show mini-map on my UI. To show all mini-map I need to set size 1200 on my camera and then I have a huge drop on fps.
I don’t know how I can improve the system. any ideas?

code to create texture
_miniMapRenderTexture = new RenderTexture((int) _screenWidth/2, (int) _screenHeight/2, 24)
{
filterMode = FilterMode.Point,
wrapMode = TextureWrapMode.Repeat,
useDynamicScale = true,
memorylessMode = RenderTextureMemoryless.Color
};

I attached camera setting

everything works well if the camera size is smaller but I think it’s obvious

Make camera high above ground and make LOD levels for all objects in scene so they render fast and simple. Otherwise, you overloading render system with rendering whole scene in full detail into minimap. Better solution is to draw map by hand and put some color dots/figures where points of interest are.
