I just received a refurbished HP Spectre x360 (4003dx). I've used and tested it for a few days only, and upgraded the OS to Windows 10 right away. Globally the computer is great, but it seems sluggish to me (takes a while to open a software for example, even when I'm not running much in the background). I expected the computer to be more respective (even though it's got i7-5500u, 8Gb RAM, 256Gb SSD). Because it's all about expectations and I'm used to working on pretty fast computer, I installed PCMark 7 1.4 and ran a full test. I got only 2900, which is a lot less than what you've got. So I'm wondering if there is something wrong with the device. Have you heard of any issues with this model, and did you change anything in the configuration before benchmarking. I've run mine at default resolution (1920*1080) ? Thanks for any insight !
