Why I Am Switching from ASUS ROG SCAR to Lenovo Legion Pro 7

[eXplode]

I am writing this post to explain why I decided to move away from ASUS ROG SCAR and switch to the Lenovo Legion Pro 7, despite having used and liked the ROG lineup for a long time.

Main issue with ASUS ROG SCAR

My biggest problem with ASUS ROG SCAR laptops, especially the 2023–2024 models, is the severe CPU power limitation introduced through BIOS updates.

After certain BIOS versions:

CPU power is significantly reduced

The BIOS becomes locked, with no option for the user to control power limits

Micro stutters appear

Synthetic benchmark scores drop noticeably

Real-world power limitation example

In many scenarios:

The GPU runs at around 80% load using approximately 140 W

The CPU is capped at around 65 W

Considering that the laptop’s total power budget is around 240 W, this means:

The CPU is not allowed to use the remaining available power

Total system power draw often peaks at only ~205 W

This results in a clear CPU bottleneck, even though there is unused power headroom.

My personal experience

I owned a ROG SCAR G16 (G634JZ, 2023) and fortunately never updated the BIOS, staying on version 318.

Users who updated to BIOS versions 331–333 widely reported:

Heavy CPU power restrictions

Locked BIOS with no user control

Micro stutters

Lower benchmark and in-game performance

Unfortunately, ASUS has done nothing to address these issues or give users back control.

Concerns about newer ASUS models

This raises serious concerns regarding the ROG SCAR 2025 models:

There is no guarantee that future BIOS updates will not introduce the same power limitations

There is no assurance that performance will remain consistent after updates

The risk of locked BIOS behavior remains

Many users have reported these problems, which significantly reduces confidence in ASUS as a brand.

Why Lenovo Legion Pro 7

When comparing systems with identical or very similar hardware:

ASUS ROG SCAR G16

Lenovo Legion Pro 7

The Legion consistently:

Performs faster

Shows fewer micro stutters

Allows higher and more stable CPU power usage

Avoids aggressive or hidden power restrictions

Conclusion

For these reasons, after selling my ASUS ROG SCAR G16 (G634JZ, 2023), I decided to switch to the Lenovo Legion Pro 7.

This decision is not emotional but purely technical, based on real-world performance, system stability, and hardware control.

I only forget to upload my stats whit BIOS 318 

And this is for asus to see temps, power usage, FPS, frametime and more 

I won to see how big SH*T is this BIOS updates ann i wont other people to see what can happen on the newest laptops that they have or wont to buy

Bro, I'm glad to hear you upgraded your laptop! Congratulations. But be prepared for the fact that L-on laptops have a poor solder compound, which is difficult to repair. The warranty will cover the costs, of course, but keep this in mind. Otherwise, if I had to replace my G16-G18, I'd also go for the L-on because it doesn't have this idiotic BIOS and driver issues.

As for lag and microfreezes, by rolling back Windows to 21H2 and updating all the drivers slightly to December 2022, I got the minimal lag possible! But gamers can't live without NVIDIA driver updates, which means an Asus laptop isn't for everyone; it's a one-time seasonal item. I'm sure most of the artificial restrictions are simply to save on licenses and protect proprietary code, but this protection causes discomfort for the end user, as it's very difficult to restore stability.

1. Clean Install 22H2 with autoupdate drivers

VS

2. Win11 21H2 (archive org) with manual install old drivers + whql mix asus proprietary downgraded (2022) bios 313

I’m glad you managed to find a stable solution for your laptop, and it’s also good that you didn’t upgrade the BIOS — that clearly helped avoid many of the issues.

For reference, here is a latency test of my laptop

Bios 318 

Windows 11 24H2

As you can see, achieving this level of latency and smoothness requires a significant amount of work, testing, and technical knowledge. Many users simply don’t have the experience or time to roll back Windows versions, mix old and WHQL drivers, downgrade BIOS versions, and fine-tune the system at such a deep level.

That’s exactly why I prefer a system that works well and remains stable out of the box, without requiring extreme manual optimization just to avoid micro stutters and latency issues.

I have other videos you can check it and aee how big optimization can be done but this is a lot of work

Very well said. I don't know what they're doing with this BIOS nonsense.
