this is the common issue my team <a href="nexodesigns.com">Design Agency in New York</a> are facing so many time.

It depends on its resolution and pixel-free angles with smoothness and sharpens variations under brands productivity with built-in software installed but some factors like update and versions are also effective like any creative artist of a logo design company in Lahore logodesigners.com.pk faces throughout projecting with freak mind finding the solution.

I made more tests (in Windows) with OP's adaptive resolution script (X-Frame), and discovered that this issue doesn't happen with the "Universal Render Pipeline".

The "Both cameras are half as wide as they should be" issue, it only happens in the Legacy Render Pipeline.
In URP, the splitscreen cameras (with X-Frame) fill the screen correctly.

Hey everyone! The first time I've visited here and try to identify and understand the different cameras. Different cameras with their different pictures result with the sharpness and different viewport Rect effect or results.

This is an urgent issue for me, because my project is a 3D game with a 2-player split-screen mode.

I plan to release a version of my game for Mobile platforms, including the split-screen mode (to be played with external joysticks connected to the mobile device).

OP's Adaptive Resolution script really makes a difference on performance for mobile, so my game can be played in lower-end devices.

But with the issue as it stands, it prevents me of releasing the 2-player split-screen mode for mobile platforms.

I'm a user of OP's custom script for Adaptive Resolution, I'm having the same issue on Windows.

Every camera viewport is different, IOS phones camera is one of the best for normal use, and as a professional photographer and graphic designer at the best logo designing service company https://logodesigner.pk/ our team had also faced this issue and they also want to know the solution to this issue.
