The Witcher 2 Gains Yet Another Performance Beta

By -
I really do have to hand it to Virtual Programming for sticking at it despite harsh feedback from a lot of people. The Witcher 2 has another performance improvement beta release.

Today (14th August) comes with:
QuotePublic Beta 4 - buildID 355503

This contains the following:

- OpenGL worker thread now goes to sleep when it can, freeing up a cpu core for other things. This really helps speed up level loads especially.
- Optimised our use of memory barriers and using coherent buffers where appropriate
- Optimised handling of fences
- Use ARB_texture_storage for texture uploads. Again, should improve level loading times.
- Optimised our OpenGL state cache

Most of these performance optimisations are best seen on nVidia hardware at the moment. Major performance improvements are expected in the near future through the work of AMD and Intel driver developer teams.

We're aware of two potential crash on exit bugs.. one appears to be nvidia driver related. We're still chasing the other one.

Source Announcement

Check out The Witcher 2 on Steam if you want to see how it performs for you, but be sure to opt into the beta.

My Thoughts
This is done on:
Intel i5 4670K 3.4GHZ
8GB DDR3 RAM
Nvidia 560ti

It's now actually playable for me on LOW settings (1920x1080) with FPS even hitting 40FPS which is a massive difference from the 10-20FPS on LOW when the Linux version initially came out. It actually feels responsive and smooth on LOW settings now.

On Medium (1920x1080) it's sadly another story with it on the exact same area hitting a max of 20FPS, and with dips down to 9-10FPS regularly. The input lag does seem to be sorted, but the game-play does still feel sluggish and not playable.

Update: If I put down the resolution to 1280x720 on MED it does go up to ~30FPS at least with a max of around 40FPS (third screenshot)

See the shots below for comparison (luckily GLXOSD now works again!):

How does it run for you now? Kudos to VP for the good support and attempts to fix it. Still, until it is playable with at least 30+FPS on MED I wouldn't call it done just yet. Article taken from GamingOnLinux.com.

So,

I benchmarked it using glxosd. I was really surprised the framerate was much lower than I would have expected. I got solid 60 FPS during the opening intro then 20-30 in game. Felt much smoother.

1920 X 1080 resolution
AMD 8320 Overclocked to 3.76 GHZ
8 GB DDR3
2 GB Factory Overclocked Nvidia 760 GTX

60 FPS in intro movie

20-30 FPS in game

I finally just gave up for now on glxosd with steam games and Arch. I'm in contact with the glxosd creator so hopefully we will work it out eventually. I went ahead and installed voglperf and used it.

With vsync
30 fps in game (60 sometimes)
60 fps for prerendered stuff

Without vsync
mostly 40-63 fps in game (seen some 70-90 fps in the intro interogation scene)
FPS off the charts in menus and prerendered stuff.

Arch Linux
AMD FX-8350
Asus sabertooth 990fx r2
8gb Kingston ddr3 1600
Samsung 250gb 840 EVO
2x EVGA GTX-580 SC
Game Res - 1920x1080

Liam, I understand you're upset with people criticizing your system etc, but we're really just trying to demonstrate our experiences.

Back in the day I was able to Fully max this game out (Uber on) with my 560 TI at 1600x900, so I wouldn't even call Mid 30fps acceptable, even if it is on Linux.

Also, It might be worthwhile to compare performance on different distros etc. Just my 2 cents, but please don't turn off the comments.

Just a suggestion, but what's your performance without SLI? I wonder if just having the one card would improve your performance as a 580 (in Windows) should be able to max this game out.

Did I miss something, or did Liam delete the comments?

At any rate, you all can come and laugh at my graphics card from 2008 if you want. I really wouldn't mind. ;)

I run the game at Ultra settings and it runs flawlessly. No lag, no crash except when I exit the game.

Have you tried lowering the texture cache size? In my case, it gave me a good performance boost before the last 2 upates. Not mentionning solving many game chrashes.

The other thing I found on The Witcher 2 Github is the fact that too many saved games makes it unstable.

Happy W2!

My setup with linux is a bit different. I have 3 1080p monitors (2 monitors on one card, 1 on the other) using nvidia's basemosaic option. Most things I play spanned across all 3 @ 5760x1080 (http://www.gamingonlinux.com/forum/topic/302/page=5). Short of turning off monitors and changing up my xorg.conf I can't exactly disable one. Maybe ill try for sh*ts-n-giggles when I feel like diggin under my desk ;D

EDIT* without vsync it does run closer to 60 fps than not most of the time.. but vsync drops it to 30 since it's stable.

Same here :)

And I think that with my GeForce 9600GT, and my Core2 @ 1.6 GHz, I should'nt even bother trying the Witcher 2

With i3570, GTX660, 8 GB and 1680*1050, I got 20(!) to 30 fps on high settings in the first open air scene. Not what I'd actually call playable.

It's good that they're working on it, it's nice to have frequent updates. But they're far from finished. And while we can be happy with games working and being playable at the moment, we will call for the same performance (more is always welcome) as on Windows some day.
