As promised I did a Twitch livestream of Feral Interactive's Linux port of Tomb Raider the day it was released. The video finally let me export it to Youtube (been trying for days) so you can now view it any time.
I noted in my port report the game had performance issues dropping down to 20-30FPS and you can see it happen in the video. At one point I could see what I can only describe as ghosting, where the graphics looked all blurry when moving as it got so bad. It's about 47 minutes in where it gets really bad at one point. I believe a few minutes later it got so bad I called it "horrific" and at that point it really was. I sent Feral a link to the livestream with the time in the video it happened, so they hopefully saw that. It was actually worse than the captured video shows, as you can't see the ghosting in the recording likely due to the settings I was streaming at.
Hopefully Feral Interactive will be able to find the causes of the performance drops and boost it up for everyone. I said in the port report they don't get a free pass with me, no one does.
Still enjoying it a lot myself, but it is worrying for people with a lower powered PC when compared with my beast. When my game drops below 20FPS I couldn't imagine playing it on a lower PC right now.
Some you may have missed, popular articles from the last month:
Quoting: linuxgamerAs people complain about Linux overall performance and frame drops, is the Mac port so much better, or do people don't complain when its a Mac thing?I have read than mac people had a good time with the port (even if it doesnt support TressFX on os x), and they get decent performance on intel gpus. This only shows than more than a port issue, we should also take a look at the drivers, is known than feral already contacted the driver devs about the issues they have with their games, so I wouldnt be surprised if in a future update performance can improve.
Another thing is than mac people somehow doesnt like to make benchmarks, as long as it works properly they are happy.

Quoting: Comandante oardoSomething must be wrong with this game. In the Linux version of the original Metro Last Light, a well known GPU demanding game, I have permanent 60FPS with a GTX 750ti, but with this game I have locked 30FPS with the same hardware, in Normal and High quality.. And the game doesn't look better than M:LL...
Metro was a "true" port, ie no middleware added on the stack. So Metro is an example of how the games would have ran is the code were "truly" native

Have the performance CPU issues being fixed already?

Performance drop in video coincides with the mist/cloud effects?

When I played the game in Wine ages ago the most demanding sections were:
Waterfalls by the wolf den
Shanty Town
And one other place I can't remember. It did seem to coincide with those alpha effects.
Even now for example if you go to the campfire by the wolf den near the beginning segments (can't remember the name of the location sorry) and look at the waterfall you'll see a massive FPS drop. If you look slightly in either direction so the waterfall is off screen it picks back up again. Only thing I can guess is that there's a stall somewhere in the pipeline with those effects.

I initially stared playing on rather high settings, then bumped into frame drops at the exact same location as Liam had. After experimenting with graphics options, I ended-up having texture quality at high, while lowering shadows/details/reflections to normal. I had no more frame drops since then (currently about 40% into the game). The game now runs very smooth on my moderate machine (1920x1080, GTX 870M 6GB, i7, 16GB RAM) and I'm bloody enjoying it!!! :) Still, my almost maxed out visuals and fluid experience of Shadow of Mordor is yet to be beaten.
