Auto Exposure Mobile Problem

Hi

i have converted and optimized legacy image effects tonemapper (eye adaptation) for mobile platform
It works well on Honor 10 Lite android device with Mali-G51 MP4 gpu without performance lost (only 1 ms overhead):



But when i tested on Samsung j5 with adreno 306 gpu, the screen becomes pixelated:



In my opinion, the only thing that can cause this problem is RenderTextureFormat

What RenderTextureFormat do you think is suitable for poor mobiles?

Code (CSharp):

1. private bool CreateInternalRenderTexture()[/B][/B]
2. [B][B][/B]
3. [B]        {[/B]
4. [B]            if (rt)[/B]
5. [B]            {[/B]
6. [B]                return false;[/B]
7. [B]            }[/B]
8. [B]            rtFormat = SystemInfo.SupportsRenderTextureFormat(RenderTextureFormat.RGHalf) ? RenderTextureFormat.RGHalf : RenderTextureFormat.ARGBHalf;[/B]
9. [B]            rt = new RenderTexture(1, 1, 0, rtFormat);[/B]
10. [B]            rt.hideFlags = HideFlags.DontSave;[/B]
11. [B]            return true;[/B]
12. [B]        }
