Quote from: Arc B390 bad 1% FPS lows on March 02, 2026, 17:34:09YouTube/Just Josh measured bad 1% FPS lows of all Arc B390 laptops (youtu.be/jduWl1J_4lQ?t=630). This is disappointing and I hope it can be fixed.

I wonder if the 120 Hz (same as display' 120 Hz refresh rate), 14%, PWM amplitude is going to be an eye-strain issue.

This device is advertised as a PWM king already. I am not sure if what PWM results say here is correct. The PWM should be 4320Hz. I had 2025 version of this device, and did not experience any eye strain.

So the arc b390 is the best we have for now. Yes, it isn't strong enough, wish it was a bit stronger but it is what it is.

Maybe fine wine driver updates can improve things with Microsoft's DirectX update that deliveries 90% performance boost on arc battlemage using SER can help.

I hope JJ tests more games on battery and not just Forza.

Fundamentally, wattage (influenced by thermals) is the limiting factor. As to whether or not a particular GPU is "strong enough", it's always been about managing the workload. For gaming, that means dialing down the settings.

Here is another video with bad 1% FPS lows of Panther Lake's Arc B390: youtu.be/A_jHa0d1aFA?t=319 (YT/Just Josh: "Intel's New Integrated GPU vs 10 Popular Games (Shockingly Playable)")

Quote from: youtu.be/A_jHa0d1aFA?t=319..we wouldn't recommend it. The 1% lows and .1% lows are just too rough.

This SOC is a winner. Incredible levels of CPU efficiency and iGPU performance. Real-world gaming being basically equal to B390 is a pleasant surprise too.
