CryENGINE 3 Free SDK With Stereo 3D Support is Now Available

August 18th, 2011 · 3 Comments · Stereo 3D Games


Great news everyone as today Crytek has released a freely available CryENGINE 3 SDK for non-commercial use, you can download it and try it out, you just need to do a free registration in order to be able to use it. The CryENGINE 3 Free SDK can be used for non-commercial projects, so you can use it for educational purposes or even to make your own games and distribute them as long as they are available completely free. And things get even better as the CryENGINE 3 Free SDK also offers full support for the stereoscopic 3D output modes that were available in the game Crysis 2 that is based on this engine. And although the game itself only contained the post stereo rendering, meaning not full dual frame rendering as a means to still provide decent feeling for volume of the objects on the scene almost without sacrificing any performance, the free SDK also offers you to use dual rendering mode. This means that you would be able to make full stereoscopic 3D rendering for both images intended for the left and right eye, but this comes at some cost, namely the bigger hit in terms of performance when in stereoscopic 3D mode.

The Post Stereo mode (SSRS or Screen Space Re-Projection Stereo) is the only option affordable for consoles according to Crytek in this SDK as Xbox 360 and PS3 generally lack the power to use dual rendering on more complex gaming environments that you’d be normally designing with the CryENGINE 3 engine. The trick behind this is that the image for the second eye is extracted from the one rendered for the first eye by offsetting pixels based on the depth, so the processing power required for rendering the frame for the second eye is significantly reduced and thus the drop in performance drop is hardly noticeable. However when working on a game for PC you’d probably prefer to use the Dual Rendering mode in order to get two fully rendered frames for each eye in order to have more convincing depth effect, of course provided that you have powerful enough video card that can handle the extra load. Both the Post Stereo and the Dual Rendering modes are fully implemented in the CryENGINE 3 Free SDK, so you will be able to experiment with them to see what the visual and performance difference are.

CryENGINE 3 Free SDK System Requirements [Developer]:

– Supported operating Systems: XP, Vista, Windows 7 (with Windows 7 recommended)
– CPU: Intel Core 2 Duo 2GHz, AMD Athlon 64 X2 2GHz or better
– Memory: GB RAM (4 GB recommended)
– Video Card : Nvidia 8800GT 512MB RAM, ATI 3850HD 512MB RAM or better

CryENGINE 3 Free SDK System Requirements [End User*]:

– Supported operating Systems: Windows XP SP2, Windows Vista SP1 or SP2, Windows 7
– CPU: 32-bit or 64-bit processor (a multi-core processor is strongly recommended)
– Memory: 1 GB RAM (2 GB recommended)
– Video Card: ShaderModel 3 capable graphics card (for example an Nvidia 6 series card)
* End Users who only use the game launcher without Sandbox have lower system requirements.

The only new feature that the CryENGINE 3 Free SDK still lacks is the support for DirectX 11, but apparently such will be added in a later version of the SDK, so you will also get to use that feature.

Crysis 2 DirectX 11 Ultra Upgrade Now Available Along With Patch 1.9

June 27th, 2011 · 23 Comments · Stereo 3D Games


When the game Crysis 2 was initially released it was clear that the game has been developed with console gamers in mind and PC gamers were kind of left with not so impressive graphics, the game initially supported only DirectX 9 mode. The side effect was that the game was running very well even on not so powerful hardware, something that we were not used in seeing from Crysis as up to the release of Crysis 2 the game was one of the most demanding ones when you are running it with maxed out detail and effect levels. No things are finally getting back to their right place with the release of patch 1.9 along with some extra high-res textures and DX11 support for Crysis 2, adding DirectX 11 support along with tessellation and some other extras along with the new Ultra mode for really high-end systems.

The DX11 Ultra Upgrade is a free visual improvement add-on introducing DirectX 11 support as well as a wealth of graphical improvements and performance optimization for both DX11 and DX9 API’s. When using the new “Ultra” spec, DX9 platforms will benefit from real-time local reflections and contact shadows. The owners of DX11 platforms, in addition, will be able to enjoy hardware tessellation (requires the installation of the “DX11 Ultra Upgrade”), parallax occlusion mapping and several improvements for shadows, water, particles, depth of field and motion blur.

Apparently DirectX 9 gamers will also benefit from these updates, but I should point out that there is no single word about any stereoscopic 3D improvements, new features or changes in this patch and extra features going along with it. There are however some important things that you should know that are mentioned and are currently considered issues that are going to be soon resolved: Crysis 2 may flicker on the SLI-enabled configurations having a GPU dedicated to PhysX (no matter if PhysX is enabled in NVIDIA control panel). 3D Vision does not work on 64-bit systems (dx11-only issue), as a temporary solution you are being advised to switch to an older driver version as this might temporarily solve that issue and probably it will be resolved with a driver update by Nvidia along with the SLI problem also mentioned above. There is also an issue that may cause anisotropic filtering to get disabled for DX9, the temporary solution for the moment is to force it through the control panel of the video drivers. If you try the new DX11 support in stereoscopic 3D mode you ar welcome to share your feedback below…

List of Upcoming 3D Vison Ready PC Games Expected Soon

March 6th, 2011 · 9 Comments · Stereo 3D Games


I haven’t written about upcoming 3D Vision ready games for a while now, but considering it is not always something game developers announce early in their game development stage, it is expected to get such information close to the title’s release. So here are a few games that will be 3D Vision ready or support 3D Vision with Excellent rating that are going to be available soon and that are worth checking out if you are wondering what your next game to play in stereo 3D mode should be…

Bulletstorm. I know this game has beet released already for about two weeks, but the thing is that at its release there were no newer drivers from Nvidia and a 3D Vision profile for it to enjoy the game in stereo 3D mode as it was originally intended. In the past week Nvidia has released two beta drivers 267.24 and 267.31 with the needed profile, so if you want to play it in stereo 3D you need to download and install one of them. The game is quite nice and feels really great when played in stereo 3D mode, especially when you are doing all the stunts with your character around the virtual world you play in.

Homefront. This is an FPS game that is soon expected to be released for PC, Xbox 360 and PlayStation 3 and to be more precise on March 15th in North America, March 17th in Australia, March 18th in Europe and April 29th 2011 in Japan. However only the PC version of the game will support 3D through 3D Vision, with the version for computer gamers also featuring more additional extras as compared to the console versions. So the developer apparently took the time to really make the PC version something that is worth playing and not a crappy console port, but that of course needs to be verified.

Assassin’s Creed: Brotherhood. Brotherhood is the direct sequel of the previous Assassin’s Creed II and is the third game in the series, the console versions for PS3 and Xbox 360 are available since November last year, but the PC version is expected on March 18th in Europe and on March 22nd in North America. The reason for the delay of the PC version is due to optimizing the game for better stereoscopic 3D gameplay as well as some extra features, including multi-monitor support for AMD’s Eyefinity technology.

Crysis 2. This is a much anticipated title due to the popularity of the franchise and the fact that the developers of the game have worked on adding native stereoscopic 3D support in their game engine, allowing them to make the game 3D-ready on consoles as well as on the PC, so the PS3 and Xbox 360 versions will also support 3D. Now since the game uses an internal rendering technique for producing the 3D views – some call it “fake 3D”, but the end result is very decent and apparently does not lead to significant performance drop (crucial for console gamers), on the PC the 3D Vision is only used for the visualization. Still the game is worth checking out, there is already a Multiplayer demo available for a while that you can try in 3D if you still haven’t, before the actual game arrives later this month, more specifically on March 22nd in North America and March 25the in Europe.

Fable III. Another game already available in a version for Xbox 360 since October last year, but coming with a PC version on May 17th in North America, May 19th in Australia and May 20th in Europe. The reason for the delay of the PC versions – exclusive extras being added in the PC version, such as a special hardcore mode of gameplay as well as support for 3D Vision. Is the extra time dedicated for the PC version worth the wait, we’ll have to wait a bit more to see, but the game can definitely benefit for a goo stereo 3D mode support a lot, so keep your fingers crossed here.

The Witcher 2: Assassins of Kings. This is a fantasy RPG game that is expected to be available on May 17th and it is the only one that will be PC only, meaning no console versions – it has been made for PC gamers. The information about stereoscopic 3D support is not widely commented yet, but there is an official confirmation that the game will support 3D Vision and hopefully the game will be even better than the first Witcher.

Now, you probably see that lately more and games more games are coming out first for consoles and the PC version gets some delay and is released after a few months with some extras. This may seem as a bad thing for some gamers, but I’d actually prefer it that way if the extra time is taken to make the PC version of the game able to take advantage of the extra graphics power a PC can provide, the game controls are optimized for PC gameplay and so on. I prefer a little delay, but to get a good PC game and not some rushed and crappy port from a console version, what about you?
