New PS5 user with some questions! Please help.

[kashif]

Hello everyone. Got my PS5 yesterday. I was waiting for price drop but seemed like it isn't gonna happen anytime soon so I thought to eventually get one. I have yet to open it. I have some questions please:

1) It has two modes. Performance and Resolution. Performance focusing on framerate while Resolution focus on graphics. But what about the Fidelity mode some people mention in youtube comparison video? What's the purpose of it?

2) I have a sony X900h that supports hdmi 2.1 VRR @120htz but if the PS5 is VRR supported yet? Also if enabling that mode will have graphics compromised? I am not a hardcore gamer so for me visuals are more preferred than fps so please let me know what settings shall I choose?

3) About my existing PS4 games (Physical and digital) will they play better on PS5 or will look the same? Is there any mode to enable to play PS4 games on PS5?

4) Does PS5 supports both Dolby Atmos and DTSX for 4k Blu Ray movies?

5) Also since I have no idea about the system so anything you want me to tell as a beginner I would highly appreciate that like tweaks or things I need to do to get maximum good experience from my PS5.

These are my initial questions. I may need to ask more questions so I ll update this thread from time to time.

Thank you.
