I recently bought a Surface Book 2 13.5’ for uni and the occasional gaming. I really only play Overwatch and I have been suffering major FPS issues. I connect my laptop to a external monitor AOC U2879VF via a USB-C to HDMI adapter. It has a 1050 GTX and i7-8650U CPU. I have a fan blowing onto the back of the laptop (on the Windows logo) and charger plugged in with the slider at ‘Best Performance’ when I play.
When I play on the laptop monitor, on 1920x1080 75% render and all settings on low/off with 300 FPS cap, I easily get above 100 FPS. GPU usage hits 99% and CPU hits around ~65% with both hovering around mid 50°C.
However, when I connect to my external monitor my FPS decreases dramatically with the same settings. The GPU hits 99% but then decreases to <50°C and CPU decreases to around 20% and <50°C. My FPS drops to <50.
I do not understand why there is a major decrease in performance when I am connected to the external monitor compared to the laptop monitor. I use MSI Afterburner to monitor these % and °C. The integrated graphics aren’t being used when connected to the external monitor since the % usage stays the same. I’ve searched for this problem with other users and I haven’t found anyone with the same issue as me.
I have tried many potential fixes like disabling HEPT, setting OW to use NVIDIA GPU in NVIDIA control panel, ticking ‘Disable full-screen optimisations’ in OW properties and deleting the OW ‘Settings_v0’ in OW folder. I use Driver Easy to check for updates and my NVIDIA GPU driver is up to date. I am truly stuck, please help.
