The Witcher 2: Assassins of Kings Enhanced Edition Released For SteamOS Linux

UPDATED, See the bottom!

That's not an error, The Witcher 2: Assassins of Kings Enhanced Edition is now out for SteamOS/Linux and I am downloading it as I type this. This is truly a knock-out year for Linux gamers and it's only May!

Warning: Radeon graphics cards are not supported, Intel integrated graphics chipsets are also not supported. This commenter points out why. Interesting to see AMD fix their drivers so quickly, I hope more bigger games come out forcing all graphics vendors to improve.

One thing I mentioned before is the coming of "SteamOS" rather than Linux, it is becoming more frequent quickly and I am actually okay with that. Linux has been a scary word for developers for too long, but no more!

There have been hints at this happening for months and I am extremely pleased to see it turn out well for us.

Be warned it's a hefty 15.8GB download, so prepare for a wee bit of a wait. Grab a beer a relax while watching that download bar, or just play something else...

About

The player is Geralt of Rivia, a professional monster slayer, a witcher. Entangled in the political turmoil that engulfed Temeria, Geralt helped quell the rebellion of the Order of the Flaming Rose. Soon after, he saved King Foltest’s life when the monarch was attacked by a witcher-like assassin. He continues to protect the king, serving as his bodyguard as Foltest strives to bring peace to his kingdom. The Order’s last bastions have yielded to the royal army, yet one more task remains - the Baroness La Valette announced her secession from the realm, and her fortress must be taken. A month after the attempted assassination, Foltest’s armies stand at the gates of La Valette Castle, preparing for a final assault. Still at Foltest’s side, Geralt is among them, unable to begin his personal quest to discover the mysterious assassin’s origin and identity…

The great thing is that it's also 80% off to celebrate! Get it on Steam now, seriously go get it right now.

For those who own a boxed copy of it, with GOG.com supporting Linux this year I suggest you go here and reedem your backup copy on GOG. While you won't get a Linux copy yet I imagine in future you would.

You can also thank the developers directly on their official forums post on it.

UPDATE
It's no wonder people are experiencing poor performance issues, it looks like it uses a wrapper called "eON" from Virtual Programming who did the Mac port. This porting technology is new to Linux, so perfect performance isn't going to happen right away.

Personally I am displeased by this as the performance on the lowest setting for me isn't great and my rig is pretty damned powerful. I am actually glad I didn't pay full price as it's unplayable. I don't mean to be too harsh about it (I don't like to sugar coat things either), but when there's so many people claiming the same thing then something is up, but this "eON" tech is new to Linux, so there's always room for improvement.

If you scan around the files, you will note these:
eONprecompiledShaders32.dat
witcher2.vpfs
VPFS_registry.vpfsdb

Pretty obvious it uses their eON tech. It wouldn't be so bad if it didn't run so terribly, I've said before that I am glad our purchases count for Linux rather than Windows, but for newer games it just doesn't feel right somehow.

What do you think to this information?

UPDATE 2
A developer from the porting house who worked on this has done a few posts in the Steam forum topic on it. You can see one such post here, there's also a funny one here where the developer is sadly making rather uninformed statments:

jaycee1980Remember the binary Nvidia and AMD Catalyst drivers only tend to support newer hardware.

I wish developers would research a little more before saying such things, as it doesn't do their reputation any-good.

Both teams need to do some damage control I think and get down to fixing issues ASAP. Two things to check is if Vertical Sync and UberSamping are both off as both are known to cause problems, but sadly for me I still cannot play on the lowest possible settings.

Not the best of launches.
