With my Intel Haswell Iris Pro 5200 system I need less then 3 Minutes to get into the game and play (continue from save). You say you need 20 Min? I use Matts patch of course. What I see is that video-play and shader compilation all run on one cpu core out of 8. What a waste! The videos (original from the movie) are all blocked by shader compilation. I don't think this is the intention from the game developers. To split video and shader compile into at least two threads should already bring better loading times and makes total sense. And as far as I know this is the part of the OpenGL driver and not the application. Mesa+radeonsi seems to run fine, look here... <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - [radeonsi] Alien: Isolation feature request" href="show_bug.cgi?id=93144">https://bugs.freedesktop.org/show_bug.cgi?id=93144</a> In <a href="show_bug.cgi?id=93840#c31">Comment 31</a>... <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - [radeonsi] Alien: Isolation feature request" href="show_bug.cgi?id=93144#c31">https://bugs.freedesktop.org/show_bug.cgi?id=93144#c31</a> Edwin Smith from Feral is happy to help.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
