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…

Trying the Game Portal 2 in Stereoscopic 3D Mode With 3D Vision

April 23rd, 2011 · 6 Comments · Stereo 3D Games


The game Portal 2 has been out for a few days already and I’ve decided to try it out in stereoscopic 3D mode with 3D Vision to see how good it will look with the added sense of volume. Portal 2 uses Valve’s Source engine, so expectations were high considering that the engine does perform quite well in stereo 3D mode. I’ve used the latest 3D Vision drivers version 270.61 WHQL that do come with an official profile for the game and in it Portal 2 is rated as providing Good experience in stereo 3D mode, but it is actually better than that, although not completely issue free yet.

Generally the game looks great in stereo 3D with the default settings and the 3D Vision profile, even the crosshair is rendered in 3D, the only thing that may be a bit of bother is the fact that the traditional game colors are very contrasting and with higher depth levels you may see more crosstalk/ghosting (just as was the case with the first Portal game). Another interesting thing that I’ve noticed was the fact that with SLI enabled when panning the portal gun movement is stuttering a bit in stereo 3D mode, creating a weird feeling, disabling SLI fixes the issue. There might be some other small issue during the game, but in general there are no serious issue to prevent you from enjoying the game in stereoscopic 3D mode with 3D Vision.

Nvidia is already aware of the issues in stereo 3D mode and they are working on fixing them, with the fixes expected to be available in the next 3D Vision driver update, here is what they noted as possible problems:

– Minor artifacts on water throughout the game.
– At the beginning of Chapter 8 (The Itch), the main NPC uses Video screens to watch and talk with you. In one eye the image is incorrect; half of the NPC is solid black like a bad shadow or texture.
– Using NVIDIA SLI with all in-game quality settings set to max, there is some image corruption. For example, objects will only render in one eye, polygons may appear stretched and shadows may be bad. You can work around this by configuring the antialiasing to any setting below 16x and setting anisotropic below 16x.



The 3D Vision profile provides a decent default convergence setting, however I did a testing to make it slightly better, so you can just tweak a bit the convergence with Ctrl + F6 in order for your Portal gun’s closest part not to seem doubled when not looking through the shutter glasses. You can see the above screenshot as an illustration of what I mean, click on it to see the full side by side screenshot and save it on your PC as a JPS file to view it in 3D. And yo are welcome to share your feedback about the game in the comments below…

Trying to Play the Game Crysys 2 in Stereo 3D Mode With 3D Vision

March 26th, 2011 · 43 Comments · Stereo 3D Games


Finally got some time to try the full Crysis 2 game in single player in stereo 3D mode and I can say I’m not very impressed or satisfied with it, and that comes after my initial overall good impressions from the multiplayer demo released earlier this month. So let me get started, I’m a bit disappointed from the quality of some textures and models when viewed up close, there is no DirectX 11 support (yet), there are no advanced in-game options to control the graphics and effects levels, just a few preset modes and that is it… just like in the demo. The same thing applies for the 3D settings as well, you get no options to control depth or convergence from the in-game menu, you can tweak only the depth level a bit through the 3D Vision depth control key combination. The game uses native stereo 3D engine and thus it only outputs the 3D content through 3D Vision and does not render it through it, the engine itself automatically recognizes what 3D hardware you have and it supports multiple 3D viewing methods (the most popular ones)…

Playing the game with higher depth levels creates some possible issues, such as having problems quickly focusing on screen text messages that are being overlayed on 3D scenes in the game, although the text also seems to vary its depth positioning. Having blood splattered on the screen at the intro of the game is a bit of a problem, as the blood is in 2D and overlayed on 3D scene with some pop-out it is hard to word out the depth. The DOF effect in cut scenes may be a bit distracting in stereo 3D mode, although it works quite well in plain 3D mode. There are some stereo windows violations in the cut scenes, but they are more distracting if you try to play with higher depth, I’ve found the lowest depth level to be the most comfortable and problem free for me personally for playing with the default S3D settings. Due to the specific way of rendering the stereo 3D there seems to be a bit of a problem with the gun, you may be able to see a strange semi-transparent faint afterimage around one side of the gun that is yet again creating a weird feeling that something is not right. So you can see why I’m not way too happy with the stereo 3D in the game, at this point it is more distracting when used than to provide you with a more immersive experience when playing Crysis 2.

One more important thing for SLI owners, even if you are using the latest beta 267.31 drivers there is no SLI support for Crysis 2 with them, you need to download and install the latest SLI profile update to enable SLI support and have the best possible performance while playing the game.
