If you are an owner of Acer Aspire 3D AS-5738DG laptop you should know that this mobile computer uses DDD’s TriDef software to provide Stereoscopic 3D support for pictures, video and games, but since it is using a Horizontal Interlaced mode to create the stereoscopic 3D effect you can also use other software. This made me try the Aspire 3D laptop with iZ3D’s driver instead of the bundled TriDef software just to be sure and to check if there will be any significant difference when using one or the other software. You should know that both TriDef Igniton and iZ3D Driver still do not support DirectX 10, although both are working on adding this support and we should have it pretty soon, and as for DX11 it is still too early.

When you install the iZ3D driver you need to setup it to use Interlaced, Horizontal (optimized) mode in order to have it working as it should with the Aspire 3D laptop. You can as well use the normal Horizontal mode, but the Optimized version is supposed to provide a little bit of improvement by doing some minimal vertical anti-aliasing as opposed to just skipping the unneeded lines in normal mode, although the difference it is hardly visible and there seems not to be any significant difference in terms of performance.

The next step was to try a game that is not completely problem free when played in stereoscopic 3D mode and to measure the performance difference by using both programs to see if any of them is better. The game I choose was X-Blades, because it looks quite good in S3D mode and is not too heavy so the Radeon 4570 video card in the Acer laptop could handle it. But at the same time X-Blades also has an issue when HDR is enabled and you try to play in stereoscopic 3D mode that becomes apparent when you move the camera with the mouse around your character. It turned out that the weird “wash out” effect is present with HDR enabled on both iZ3D and TriDef Ignition and then again the performance I got from both solutions was pretty close to each other. When playing X-Blades in normal mode, at maximum details, with no AA at 1368×768 resolution I get average of about 40 fps, but when switching to stereoscopic 3D mode with the help of iZ3D or TriDef Ignition the framerate on both goes to an average of 24 frames per second. There is just a slight difference if you turn the Autofocus function of the iZ3D driver On, resulting in about 2-3 fps drop. Have in mind that these results were achieved with PowerPlay disabled for getting the top performance from the laptop as I described here Optimizing your Aspire 3D Laptop for Best Performance in S3D Mode. The end result from the comparison between the programs that allow you to turn a normal 3D game into a stereoscopic 3D game is that they perform pretty much on par with each other in terms of quality, performance and even features. Of course each of these solutions has its own small advantages, but if you’ve bought an Acer Aspire 3D laptop there is no reason for you to additionally buy a license for iZ3D Driver as you won’t get a significant improvement at this moment. When iZ3D Driver version 2.0 comes out things might get improved, but also don’t forget that DDD’s TriDef is also being updated quite frequently and you can upgrade your Acer Aspire 3D laptop with latest TriDef software for free.

First Impressions from Acer Aspire 3D (AS-5738DG-664G50Mn)

Today I was finally able to get my hands on the Acer Aspire 3D laptop for a very quick test, or more specifically the model Acer Aspire AS-5738DG-664G50Mn. It has just arrived and I was able to get my hands on one of them for a short period of time in order to take a few pictures and try a how it works in stereoscopic 3D. And actually this is the first S3D-capable laptop that I’ve seen and tried and I can say that what I’ve seen with this one was pretty good, especially considering that the price of this particular Acer model is quite attractive. But anyway, lets get to the point and see what you get and what you can expect from this laptop that is using a polarized screen and passive polarized glasses in order to achieve the stereoscopic 3D effect in movies, pictures and games with the help of TriDef’s software…

One of the most important things when considering a laptop is what are its specifications, of course stereoscopic 3D is present, but it also needs a decent set of hardware to support it good enough so that you’ll get the best possible experience out of it. So Acer Aspire AS-5738DG-664G50Mn comes with 15,6-inch screen with 1368×768 resolution (don’t forget that the polarized screen reduces the horizontal resolution in half), the processor is Intel Pentium Core 2 Duo T6600 (Dual core at 2,2 GHz), you get 4GB of system memory, DVD writer and a 500GB hard drive, as for the video cards, it is an ATI Radeon 4570 with 512MB DDR3 VRAM (the GPU could’ve been a bit faster). The laptop comes with a decent set of extras like Multi-touch touchpad, HDMI video output, integrated Bluetooth, Gigabit Ethernet, Wireless-N and so on and so on… the normal set of additional features for a multimedia laptop nowadays. Interesting news is that the laptop comes with the recently announced Microsoft Windows 7 Home Premium OS and it is a 64-bit version, which is good, considering the 4 gigs of RAM.

As I already mentioned you get passive polarized glasses and actually there are two pairs in the package with the laptop – one pair of normal sunglasses type and another one that is designed to clip on to a normal pair of glasses, for the people that need to wear prescription glasses. At first the sunglasses type seemed a little bit smaller to me, like it was designed to be worn by Asians only, but it turns out to be pretty comfortable and durable, which is also very important thing here. Anyway, if you are considering getting this laptop, you better try the glasses first if possible to be sure they will fit you right, just in case… ;)

So it is time to skip right to the TriDef software and the stereoscopic 3D you are going to get with this Acer Aspire 3D laptop. The first time you run the TriDef software you’ll be presented with a setup screen to adjust your laptop in the best possible position in order to fully experience the depth effect. This means that you need to be viewing your laptop’s screen from at least 60 centimeters, which usually is around the normal distance you’ll be using it and to adjust the angle of the display. You’ll be doing that with the polarized glasses on, looking to the red roses, which should be visible with the perception of depth, so moving back and forth the screen you’ll need to find the angle at which the effect is at its best. For me personally this presented a bit of an issue, because the actual angle of the screen with the best stereoscopic effect seems to allow just about 10-15 degrees of freedom, otherwise I start to loose the depth and in turn see a little bit of ghosting around the objects presented in S3D. This is a little bit annoying, but I guess that after some time of use you’ll be able to naturally find the best position of the screen for the optimum effect and it won’t be an issue anymore.

Now, Ive already said that the polarized screen and glasses that you are going to wear have a little bit of a disadvantage in terms of the technology that is being used, compared to some other solutions, although it also has some advantages too. The biggest disadvantage is that when in S3D mode you are going to “loose” half of the horizontal resolution in order to achieve the depth effect. Now this is not that bad as you may think it is, because for watching movies and looking through some pictures while in stereoscopic 3D mode they will still look very nice, especially if you increase a bit the distance between you and the screen. But when we are talking about playing games in stereoscopic 3D it might be more problematic, because things like smaller text for instance becomes harder to read and maybe even impossible at times and also some finer details might not be that apparent to you. Still gaming in S3D is very nice and interesting even with this more affordable solution and most of the people that see stereoscopic 3D in action for the first time are really very impressed. The few demo videos and pictures that do come pre-installed on the laptop seemed very nice to look at, but it is a bit of a shame that Acer did not think of also bundling some sort of a game that looks nice in S3D with the laptop…

This is what I can share for the moment from my first 15 minutes playing with the Acer Aspire 3D laptop and of course next week I’ll also try to play a bit more with the TriDef software to see what it is capable of and how well it works on this setup from Acer. And I’m also eagerly awaiting for Asus with their G51J model (Asus G51J-SZ028V) that will feature 120Hz LCD screen to go along with Nvidia’s GeForce 3D Vision shutter glasses as a bit more expensive alternative to what Acer is offering.
