Ravensword: Shadowlands Unity 3D engine game have serious lagging in Eastern Forest after entering East Gate. I think there is a software fallback or something alike occuring in that particular level. I have traced with apitrace, the last part of trace file contains the problematic area.
Mesa 10.2.0-devel (master branch)
Intel GMA 4500MHD (device id: 2a42

Hi. I am able to reproduce the issue on my PC (see lags on apitrace + flickering screen in the end)
OpenGL version string: 3.0 Mesa 18.1.0-devel (git-1e36fe5dc4)
Dual core Intel Core i7-7500U
Intel® HD Graphics 620 Kaby Lake
Kernel: 4.13.0-37-generic x86_64 (64 bit)
But looks like the game was excluded from steam and not actual anymore.
