Question Gaming laptop strangely dropping FPS significantly

[SamK123]

Hi guys,

I recently purchased Acer Helios Neo 18 - i9-1400, RTX 4070, 32gb ram.

While playing Counter Strike 2 today, on dust 2 map, my FPS was barely reaching 150, and was commonly dipping down below 100. I contacted Acer and they made me update my VGA from their website which was nearly a year old, as well as to reset BIOS. When I started playing CS2 again, my FPS started to reach up to 250 on that map and it was constantly above 200. I discovered that my nvidia control panel it was switched back to Optimus while previously I had it on GPU only, and this time GPU only was greyed out and I couldnt choose that option.

I googled that why this was greyed out and somebody had written that they changed their settings in BIOS to GPU only, so I did the same and finally could chose GPU only from nvidia control panel.

Acer made me run Fur Mark to test GPU and that thing kept running for 1hr15 minutes before I was told by another agent to check the memory function which restarted my PC. The previous agent tht told me to run Fur Mark said depending on laptop, it generally runs for like 15 min, and after that it should give results.

I didnt get clear answer from Acer after spending over 2hrs with them. I hope someone can tell me whats going on, is the GPU on this toast?

I need this laptop for work, and being disabled cannot take it to the store to get it fixed. Will have to ship and wait for shipment back to me. Bought this open box from Bestbuy, very mad that they probably sold me junk. Btw I updated back my GPU from Nvidia experience to latest driver, the fps was again extremely low, like 140s to barely reaching 170s etc sometimes higher spikes, while on Optimus, it was constantly above 200.

I had briefly tried Asus Strix 18 with exact specs, just higher display hz, and on some maps, FPS was even like 320s or so, and I should be getting exact same results on this laptop as well.

Go into nvidia control panel and click on the 3D settings on the left of the page. Scroll through the 3D settings and make sure its set to High Performance where you can select it.

Power Management mode = Prefer Maximum Performance

Texture Filtering-Quality = High Performance

Then click Apply > OK then reboot and try.

Hi KingLoki,

Thank you for your suggestion. I did follow your steps and after rebooting when I launched the game, there is noticeable increase in FPS. I have only tested on Dust 2 map and I was getting between 160-220 fps, which is on average 50fps lower when it was running on Optimus.

Also the FPS felt it was shifting too fast like one sec it would be around 160s and than would suddenly pop to 200s etc. But on Optimus it felt more even and not jumping around too fast.

I should also include that I also have two external monitors connected for work only. One is through HDMI and another with USB C. While my computer was running on Optimus, my USB C monitor wouldn't come on, and when I switched to GPU, than it started to work again.
