Description Md Imam Hossain 2014-03-08 13:13:08 UTC

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.


Ubuntu 13.10
linux 3.12.0-031200-generic
Mesa 10.2.0-devel (master branch)
xf86-video-intel 2.99.905
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
Ubuntu 16.04
Kernel: 4.13.0-37-generic x86_64 (64 bit)

But looks like the game was excluded from steam and not actual anymore.

There is some flicker at the very end when the user goes to the menu to exit the game but that could be due to a bad trace. The performance in the forest is fine on my Skylake with recent Mesa.

apitrace suggest the game could do a number of things to improve performance, but its likely the real issue here is that GM45 just isn't very powerful.
