    Hi
    I just got one of these a few days ago and setup the [PSUserConfig] file to fix the Alt + Right Click brush settings and was really upset that Hp didn't include the Options... button to select side switch mode to: Click & Tap. This is not the biggest deal, but it would have been prefect if included. If i update drivers from Wacom, to connect my Intuos or 22HD, the Click & Tap are saved, only if i restore settings from my desktop.

    Anyways, my biggest problem now is the performance in PS cc. I paint / render in PS and when the brush size gets larger then 400 px, its unreasonably slow. Is there a known issue or a setting change that I need to make to increase the brush speed? I have the base cpu 7500u, 8gb ram and m620 Quadro. If this is just what you get with a i7 dual core, then just tell me my cpu is the bottle neck, but from what I've watched and read in many reviews on this cpu, it would not be a huge difference in performance. My canvas z 4770hq and Macbook Pro 2.9 -15 1st gen touchbar are blazing fast in PS rendering. No lag unless you do over 1k px brushes.

    Im coming from a VAIO canvas z, and this ZBook all that i was looking for. I only bought it because it was $899. The discount was just as good as my Canvas z, so i had to jump on it. The quality of the casing is amazing... I'm so impressed, and the keyboard is very nice and solid, not stamped ALU like the canvas z. Is there any way to keep the lights on the keyboard without having it sleep?

    Any comments are appreciated,
    TIA!

    The i7 7500u isn't a particularly powerful cpu so a 400px brush might very well bring it to its knees depending on the complexity of the brush.
    You could try adjusting the gpu usage preferences: at least on the Surface Book 2 it makes a lot of a difference when it comes to Photoshop Brush performance, so who knows it might be the case with the Z Book too.

    Do you think more ram would help? I can easily upgrade the ram from 8 to 16gb.

    I just upgraded to the 8550u with 16gb ram, and the difference is night and day. the quad core is huge improvement over 7500u. I compared my 7500u x2, to an i5 mobile studio pro 16" and the mobile studio pro was much faster. i dont know if there was extra bloatware slowing down the 7500u x2? Either way, i'm not sure if i will return the 8550u x2. its very nice and the speed is fast enough

    @apogee : I don't think that you need to look any farther than the 7500's basic performance as compared to the 8550:

    The 8550 has significantly stronger single- and multi-thread scores and lies much higher up in the rankings...

    Also, not sure if your 7500 X2 has the M620 discrete GPU, but the 8550 does by default. The M620's G3D score is almost three times higher than the 7500's native HD 620 graphics (2813 vs. 924). That alone could be your performance boost...

    (Credit to PassMark for these scores)

    I find it interesting that the canvas z with an 4th gen 4770hq cpu is ranked ranked higher then the 8550u. How does the 6920hq stack up to the 8550u?

    1900 vs 2100 isn't a significant difference in power. At least not enough to see much difference in brush performance in Photoshop. ;)
