Does anyone know if the Legion 5 144hz screen supports Gsync?

Supports Freesync Premium.

I, too, got the email from Lenovo asking me to be patient with their processing.

I ordered a full kitted Legion 5 Pro 16", and I am still showing a Dec 7th arrival.

Same email and date. Whatever keeps our laptops and them safe right? The date appears to be a placeholder for a pool of orders/

So does this mean that I have to use Amd optimus( run the rtx 3079 thru the Amd Vega card to get free sync ) or can I use the mux to enable discrete gpu and use the rtx 3070 solely and achieve free sync ?

In order to prevent screen tearing, you have a couple of options:

For the L5P laptop screen, you can toggle the mux switch to turn optimus on (enables hybrid mode; dGPU signal routes through iGPU; FreeSync) or off (disables hybrid mode; dGPU only; G-Sync).
For the 17 inch L5 laptop screen, you will need to turn optimus on since the screen is FreeSync Premium only.
For external displays, since the HDMI and display ports are connected to dGPU only, you will need to use a G-Sync compatible monitor/TV/display.
- Some FreeSync displays, but not all, are G-Sync compatible either officially or unofficially.
- You can view the list of displays that are officially G-Sync compatible here: https://www.nvidia.com/en-us/gefo...ors/specs/
- Normally, you will have to connect via one of USB-C ports that support DisplayPort, but there are a select number of TVs that support G-Sync via HDMI.
For all displays, as an alternative solution, you can enable VSync, which is a software-based solution. This works pretty well for eliminating screen tearing, but increases the input lag significantly more than the other options.

Legion 5 17" has a MUX switch which is nice, but saw in one of the reviews that Freesync is available only when MUX is disabled (or in Hybrid mode only).

There is a good review of the exact, maxed out Legion 5 (17") model. Should answer most of our questions:

https://www.youtube.com/watch?v=BCtSczRbQOA

Summary of the video

Overall, screen is great (3ms, 100% SRGB, Freesync), but currently, Freesync is available only in the Hybrid mode. No freesync when MUX is enabled!
Performance (by default / with stock RAM):
- Timespy - 10469 (Graphics 10753 / CPU 9109)
- Shadow of Tomd Raider (1080p, Highest setting) - 105 fps
- Cinebench R23 - 12602 (Multi + Single core)
- Warzone (1080p, Hybrid mode/freesync ON): 105 fps
- Warzone (1080p, Hybrid mode/freesync OFF): 117 fps
Thermals: GPU has great thermals but CPU hovers around 90 degrees (both in Cinebench and Timespy)
Laptop comes with "bad", 1Rx16 RAMs. Swapping them with "good" RAMs did improve performance significantly. He has also created a great video of it - https://www.youtube.com/watch?v=FKLPp4aK0UE [youtube.com]
- The upgraded RAM kit he got - https://www.kingston.com/dataShee...BK2_32.pdf
- Game1
  - Shadow of Tomb Raider (Stock RAM): 105 fps
  - Shadow of Tomb Raider (Upgraded RAM): 121 fps!
- Game2
  - Warzone (Stock RAM): 120 fps
  - Warzone (Upgraded RAM): 135 fps
- Game3
  - Cyberpunk RT Ultra, DLSS Quality (Stock RAM): 56 fps
  - Cyberpunk RT Ultra, DLSS Quality (Upgraded RAM): 62 fps

Thank you! I was wondering how well it would be able to run Warzone!
Also, that should be a featured comment!

Also, it looks like the TDP of the 3070 in the 2021 17 inch Legion 5 is 140W instead of the 130W erroneously reported on the Lenovo website, as shown in this Legion comparison video: https://youtu.be/7TgrL7gHc48?t=4470

140W is the max GPU power of any laptop 3070, so that's good.

Some other YT videos of interest I found helpful for reviewing the not really well covered yet 2021 17 inch Legion 5 (17ACH6H) with 3070 include:

maybe its 130w + 10/15w of boost or whatever?

I'm pumped to get the 17" version to replace my Costco MSI from last year. I just hope I can output to my freesync monitor and use it as a suitable desktop replacement

use a usb-c to displayport cable, and you'll be fine

I think laptop 3070 performs like desktop 3060 from reviews I've read ?

Thanks the one comparing the size difference between the pro and the non pro was helpful.

I just got an Asus G15 with a 6800m. I'm still within my return period. Should I return and keep one of the Lenovo's instead? I was able to order one of each, assuming they actually ship. I'm mainly going to be using it for warzone on the go.
