So I received my new ThinkPad P52 laptop and quickly installed Zwift to see the 3D performance. I changed the resolution to 1080p in the settings. I could not see the two higher options.
I analyzed the log file and Zwift is refusing to go above the medium profile.
This laptop (ThinkPad P52) has a new XEON E-2176M hexacore with 32 GB memory, an Nvidia Quadro P2000 video card with 4GB ram running Windows 10 x64 1803. The screen is a 4K 3840x2160 (60Hz) screen. It is a laptop designed for 3D work. I changed the two recommended settings for NVidia for the best performance. It never chooses a profile above medium. And this video card has a performance benchmark 50% better than those recommended for 4k support.
I copied the ‘ultra.txt’ profile over to ‘medium.txt’. The log file analyzer shows a resolution of 1080, shadow res 2048 with an average frame rate of 89. OpenGL 3.1.0. It all runs perfectly.
So why will it not choose a higher profile or allow a higher resolution. Whether the display scaling is set to 100% (full 4K) or 200%, I never see any other options or changes in the chosen profile.
Any ideas ?
