ASUS ROG Zephyrus G16 GU605CR

I’m very stressed about my FPS. This is a very powerful gaming laptop with excellent components, but I’m getting really poor performance in games. My specifications are an NVIDIA GeForce RTX 5070 Ti, 32 GB of RAM, and an Intel Core Ultra 9 processor.
Even in demanding games, my FPS never goes above 110. I’ve tried everything I can think of to improve performance. I’ve set my laptop to maximum performance and tried many different methods, but nothing has made any difference whatsoever.
Could you please explain why this is happening and help me understand whether there is a problem with my laptop? With these specifications, I expected much better gaming performance, and I’m frustrated because I haven’t been able to find a solution.

2026 zephyrus uses a lot of ram doing nothing.

i just purchased a new 2026 G16 and just not having anything open even upon the very first start i was having 30% + ram usage and actually when i first got to the home screen after setting it up it was using 40%+. it doesn’t really make sense to me because my old windows laptop had only 8gb of ram and was using only 3-4gb when doing nothing. my new laptop is 32gb so the 3-4gb should only be 12 %. i know windows is bloated but is it really that bad? how can i optimize windows to use less ram.

Decisions, Decisions...

I am having a hard time choosing between these two great laptops. The G16 has the Intel 285HX+5070Ti and the Legion 7 has the AMD 9955HX+5070Ti. Both have an OLED 240Hz panel and I have installed Lenovos anti-glare screen protector on the legion to make it closer to the look of the G16s screen. The Legion is well made and performs better in game(20% avg bump in framerate). The G16 just feels better to use with its aluminum chassis, perfect trackpad, fuller sounding speakers, and awesome anti-glare coating on the screen. I feel myself leaning toward the G16 but am worried about it holding up for the next 3-5years with regular gaming. I plan on gaming on it for about 30hrs per week and I have tuned the power and fan profiles so that both the cpu and gpu run just shy of 80°C. Has anyone used their G16 like this and how is it holding up?

Pulled the trigger!

I’m temporarily moving to Europe for my job and don’t want to carry my desktop around. The Zypherus has had my eye for a while because I want a well rounded premium laptop, not a flashy brick of a gaming laptop that runs 2 hours battery on youtube. I was originally looking at the 5070ti model… but best buy just marked the 5080 model down $750, only $150 more than the 5070ti model. I figured this is probably the best deal I’ll get before I start traveling, so went ahead and bought it. I’m gonna throw in another SSD in its extra slot and call it a day. Yes I know it’s expensive, no I don’t really care lol.

Upgrading from my 5 year old XPS 15 with an i7 12700H, 3050ti 4gb, and 32gb of ram.

2025 Zephyrus G16 RTX 5090 suddenly thermal throttling + shutting down when booting/ restarting

Hey everyone, I'm having a pretty serious issue with my 2025 Zephyrus G16 (GU605CX, RTX 5090 / Core Ultra 9 285H) and I'm wondering if anyone has experienced something similar.

Everything was working normally until yesterday while I was playing Tekken 8. Suddenly the game started running almost in slow motion. Since then, basically every game has been extremely slow.

HWiNFO while running Tekken shows:

• GPU usage: ~98%

• GPU temperature: 92.3°C

• GPU thermal limit: 87°C

• GPU clock: 277 MHz

• GPU effective clock: ~277 MHz

• GPU power: only ~42W

• FPS: ~14–15

The GPU fan is definitely working. HWiNFO shows it reaching around 5,000 RPM while Tekken is running (CPU fan ~5,400 RPM).

The CPU seems fine. CPU package temperature was around 77–78°C, maximum ~85°C, and HWiNFO reports no CPU thermal throttling.

At idle the RTX 5090 has also been unusually hot, fluctuating around 70–85°C, although I've been using dGPU/Ultimate mode so I'm aware that can increase idle power/temperature.

There's another strange problem that started at the same time. If I try to boot the laptop with the charger connected, it sometimes reaches the ASUS logo and then completely shuts off. If I unplug the charger, I can boot into Windows normally, and then reconnect the charger afterward and it appears to charge normally.

I also tried running the ASUS/MyASUS hardware diagnostic and the laptop completely shut itself off during the diagnostic.

So as of now I've confirmed:

• GPU fan is working

• CPU fan is working

• CPU isn't thermal throttling

• GPU is hitting/exceeding its 87°C thermal limit

• GPU clocks can collapse to ~277 MHz under load

• Gaming performance and FPS is super low when this happens

• Problem also occurs on battery (performance is still extremely poor)

• Laptop sometimes shuts down during boot when AC is connected

• Laptop shut down during ASUS hardware diagnostics

I'm wondering if this could be a heatsink/thermal interface/vapor chamber issue, power delivery issue, or something else hardware-related.

Has anyone with a 2025 G16, especially the RTX 5090 model, experienced anything similar?

I'm in Japan and will probably contact ASUS for warranty service, but I'd really appreciate any suggestions for things I can safely check or try myself first.

White G16 2026 – orange stains on rubber feet after a few days

Got my Platinum White G16 (GU606) on Sept 30. The white rubber feet under the intake are already turning orange at both ends. Clean desk, no spills, and alcohol won't remove it, so it looks like heat discoloration. Anyone else seeing this on a white unit?
