vorpx-3d-driver

If I did not read that an update for the beta of the VorpX 3D driver for Oculus Rift has been released I probably would not notice (the update is available for people that bought a beta license). According to the developers of the software should update itself automatically when you start it, but in my case it was not updating itself or at least it did not give any indication of downloading and installing an update. Fortunately after running the small executable setup file that I got when I purchased my license it downloaded and installed the update, though the control panel remained absolutely the same and since there is not even an about box or check for update option (there should be) the only way I could see that I have the update version 0.6.4 installed was the files dated 15.11.2013 and the text file containing the changelog mentioning what was changed in version 0.6.4, so below you can find the full changelog of the vorpX beta 0.6.4:

New/Changed:
– Experimental 64bit support
– Added NullTracker to disable tracking completely
– Various Windows Vista related installer changes/additions

Bugfixes:
– Various changes to avoid startup crashes with Steam/Origin/UPlay games on some systems
– VR Keys mapping not working
– Gamepad mapping not working
– Default Eye Separation twice as high as intended in Geometry 3D
– Keyboard focus ‘ding issue’ with various games
– vorpX Control does not start in Windows Vista
– Disabling vorpX freezes screen in Geometry 3D (DX9)
– Disabling vorpX causes black screen in Z-Buffer 3D (DX9)
– Headtracking activates vorpX option freezes rendering under certain circumstances
– DX9 render time handling in Geometry 3D
– Potential crash issues while loading Oculus profiles
– Geometry 3D Draw Exception DeusEx HR and possibly more games (DX9)

Added Profiles:
– ARMA III (Z3D)
– Battlefield 4 (Z3D)
– Bioshock 2 (G3D, Z3D)
– Call of Duty: Ghosts (Z3D)
– Dead Space 2 (G3D, Z3D)
– Dead Space 3 (G3D, Z3D)
– Outlast (G3D, Z3D)
– Q.U.B.E (G3D, Z3D)
– Splinter Cell Blacklist (Z3D)

Profile changes/fixes:
– Battlefield 3: no 3D after ALT-TAB/Resize
– Deus Ex: Human Revolution: Support for the Director’s Cut added
– Elder Scrolls: Oblivion: nightsky/stars look weird with Geometry 3D
– Elder Scrolls: Skyrim: nightsky/stars look weird with Geometry 3D
– Fallout 3: nightsky/stars look weird with Geometry 3D
– Fallout NV: nightsky/stars look weird with Geometry 3D
– X3: Should now support X3: Albion Prelude in 3D (untested)

The most notable changes are the improvements for games that had problems running due to some sort of launcher as well as the official support for Battlefield 4, Call of Duty: Ghosts and Splinter Cell Blacklist. There is also an experimental support for 64-bit game executables, though there are still not many games that come with a 64-bit version along the 32-bit executable. And while we see good improvements in the compatibility of the software and new features, the most basic things that are a must have are still lacking like for example a proper and complete list of games that are officially supported with information what 3D mode they support, more detailed documentation about the various features and options of the software… and even a simple About option giving you the version number would be nice.

GeForce GTX 780 Ti Game Benchmarks in Stereo 3D and 120Hz 2D Mode

November 14th, 2013 · 14 Comments · GeForce 3D Vision

nvidia-geforce-gtx-780-ti-graphics-card

Just a few days ago Nvidia has updated their highest-end single GPU with the new GeForce GTX 780 Ti replacing the previous top model in the form of GTX TITAN. The new graphic cards based around the GTX 780 Ti are out in the wild already, but the question that needs to be answered is if a single GTX 780 Ti graphics card is enough for comfortable gaming with maximum detail levels in the latest games in stereoscopic 3D mode with 3D Vision as well as what you cane expect if you play on a 120Hz+ 2D monitor instead of in stereoscopic 3D mode. That is exactly what I tried to do here, by picking up some of the latest bigger game titles that were released in the past 4 months and testing them in stereoscopic 3D mode as well as in 2D mode. I’ve ended up with 12 game titles which should be more than enough to give you a good idea about the performance you can expect and before starting with the tests let us look at the official Nvidia 3D Vision ratings of these games.


3d-vision-test-game-profiles

As you can see from the 12 games only one is rated by Nvidia as 3D Vision Ready – Batman Arkham Origins, and Shadow Warrior has an Excellent rating as the game does support stereoscopic 3D mode natively and it works great with 3D Vision. On the other hand there are four top games that are sequels to popular franchises and all of them have a Not Recommended rating, these are: ARMA 3, Battlefield 4, Saints Row IV and Tom Clancy’s Splinter Cell Blacklist. The rest are rated Fair/Good and only WRC 4 FIA World Rally Championship does not have a profile, but the interesting thing is that the the latest WRC game does work quite well even without a profile and is playable even with some rendering issues in stereo 3D present.

Furthermore there are community fixes available thanks to the Helix Mod available to improve the stereoscopic 3D playability using 3D Vision for some of these games already available, these are: Castlevania Lords of Shadow Helix Mod Fix, Lost Planet 3 Helix Mod Fix and WRC 4 FIA World Rally Championship. This way we get 5 out of 12 games that are looking really good when played in stereo 3D mode (only 2 officially), the other games could be further improved witch patched or user fixes as well.


3d-vision-gtx-780-ti-benchmarks

So what is the goal of these tests? Essentially to see if the GeForce GTX 780 Ti can provide 100fps or more in 2D mode as well as 60 fps per eye in stereo 3D mode at 1080p resolution with maximum details and some AA. As you can see the AA of choice was 4xMSAA where available as at 1920×1080 resolution it is more than enough to smooth the edges while not bringing way too much of a performance hit. After all the idea is to stress the GTX 780 Ti a lot in order to see what you can expect and you should have pretty high expectations for a high-end video card like this one.

As you can see the worst results in terms of framerate we are getting are in ARMA 3 and Total War ROME II. The case with ARMA 3 is that the game itself is really demanding, especially if you want to push the details to the maximum and have really long viewing distance in the game. The case with Total War ROME II is similar – the game can also be pushed to unreasonably high graphics details, but it also has a really stressful benchmark mode that probably represents a worse case scenario you can get when playing the game with a serious battle going on. Another important thing to mention is the result in 2D mode in the game Saints Row IV, as you can see getting 64 fps seems a bit too low, but that is due to some sort of frame capping inside the game (even though vsync is disabled), the actual achievable framerate is about 100 fps with these graphical settings. All other games do manage to provide great performance on the GTX 780 Ti, regardless if you want to play in stereo 3D mode or in 2D mode with higher refresh rate. If you want to play in 2D mode at 144Hz refresh rate on a gaming monitor supporting this you might want to consider going for a SLI with GTX 780 Ti and the same suggestion applies for larger resolution displays.

In the end, looking at the results, the GeForce GTX 780 Ti can perform really well when playing some of the top latest games with maximum graphic details and extra AA filtering both in 2D mode with a 120Hz+ LCD monitor and in stereoscopic 3D mode using 3D Vision. The card is great, but what we actually need are more games with official support for 3D Vision, because as you can see from the list of games tested here only 2 were ready to be played in stereoscopic 3D mode with 3D Vision out of the box. And thanks to the Helix Mod and the active stereoscopic 3D gaming community there are fixes for additional three, and some of the other games can turn out to look great when played with 3D Vision with patches. For example Battlefield 4 and considering the fact that the previous Battlefield 3 had a patch to add stereoscopic 3D support it is a bit of a disappointment that the sequel does not support it.

If you are still using an older series of graphics cards from Nvidia like me with two GTX 580 in SLI or even a single GTX 580 or GTX 680 you might as well consider going for an upgrade to a GTX 780 Ti in order to get the best performance with a single GPU, the same applies for slower or older cards as well. If you already have a GTX 780 or a GTX TITAN, then there is not that much need to upgrade to the new GeForce GTX 780 Ti, but you might consider adding a second card of the same type. I’m definitely upgrading my water cooled GTX 580 SLI setup to a single GTX 780 Ti and I do plan on adding a full cover water block to the card to make it cooler and quieter compared to the standard air cooler. Unfortunately going for water cooling would only help in reducing the operating temperatures, but not that much for overclocking as the most limiting factor on the GTX 780 is the power limiter maximum you can set and not the temperature. The good thing is that the GeForce GTX 780 does perform great even without additional overclocking thanks to the GPU Boost that tries to maintain the maximum clock frequency for the GPU Boost, the only thing that I’m not that happy with is the default high temperature target of 83 degrees Celsius, but as I’ve already mentioned with a water cooling setup the high operating temperature “problem” is easily resolvable.

EIZO Foris FG2421 is a 120Hz VA-type LCD Gaming Monitor

November 10th, 2013 · 5 Comments · General 3D News

eizo-foris-fg2421-gaming-monitor

Up until recently all 120Hz+ LCD monitor intended for gaming (regardless if for stereo 3D use or not) were using TN-based LCD panels due to the fact that this technology provides the best results in terms of pixel response and that is something you need if you want to have a higher refresh rate. TN LCD panels may be the fastest in terms of response, however they have other no so good aspects when compared to VA-based and IPS-based panels, but fortunately we now have what seems to be the first gaming oriented 120Hz LCD monitor with a VA-based panel from Eizo (it does not support stereoscopic 3D!). If you are not familiar with the name Eizo it is probably because up until recently the company was focused on professional monitors and it just recently started making monitors targeted at gamers.


eizo-turbo-240-working-principle

EIZO Foris FG2421 is actually is not their first gaming monitor, but is the first one that is able to work at 120Hz refresh rate and as already mentioned it is nt with a TN panel. Eizo markets this monitor as a 240Hz gaming monitor, however this can be a bit misleading if you don’t read the details, in fact it is a 120Hz monitor that has a built-in processing to simulate 240Hz. Eizo calls this function “Turbo 240″ and you can enable or disable it from the OSD menu of the monitor, what it does is doubling the frames (not interpolating, but doubling) and strobing the backlight in between them and the end result is a significant reduction in motion blur. This is pretty similar to how the 3D Lightboost technology on more recent 3D Vision-compatible monitors functions, although there is no frame doubling with them. Definitely an interesting thing to see as this Eizo monitor can turn out to be a great alternative to buying a 3D Vision-ready monitor that you may not use in stereo 3D mode at all, especially considering the fact that there are no other 120Hz displays out there that use better LCD panels than TN, so if you are not into 3D and hacking Lightboost to work in 2D mode you might want to check the EIZO Foris FG2421 out. Eizo also promises low input lag (less than 10ms) and no noticeable flickering with reduced brightness by using DC control and high rate PWM (Hi-PWM) control for driving the backlight instead just PWM.
