This past weekend I installed SimVibe.
I already had two aura pro bass shakers installed on my rig, running off the game sound. While it provided a cool effect, it was somewhat limited. iRacing doesn't seem to have a lot of low frequency sounds, so the vibration was lacking compared to other racing titles.
Simvibe uses the games telemetry data to fire the shakers versus game sound, so you get much more accurate effects. Plus it's highly configurable. With all the hype it's been getting in the iRacing forums, I was excited to try it out myself.
To get it working, I first had to pick up another sound card. The software needs its own dedicated sound output. So if you're using speakers or headphones with a 3.5mm jack, you'll need another card for Simvibe. I got a cheap $30 Asus Xonar DG from Future Shop.
Simvibe has two different modes: chassis and extensions. Chassis provides directional feedback from all four corners and is the ultimate setup, but you need 4 shakers and a 4-channel amplifier. Currently I only have 2 shakers mounted on my rig and a 1-channel amp, so I selected the (non-directional) extensions mode.
There are a number of different effects you can add in extensions mode. I chose engine RPM vibration, gear shift clunk, impact, and road bumps. To get the most out of the software you really need to spend some time tweaking the settings for your particular application. I probably spent about an hour last night getting mine to a decent setting.
Overall, it's pretty damn cool. Much more immersive than using game audio alone. Now the whole rig vibrates in sync with the force feedback of the wheel, plus the extra effects like gear changes, engine vibration, etc. I'd go so far as to say that SimVibe
doubles the effectiveness of the bass shakers. And I haven't even experienced the directional chassis mode yet. I do have two more shakers (for a total of four) but don't have a 4-channel amp to run them. Will get one soon.
So is it worth the price of admission? I'd say not.
Maybe if the whole setup could be had for < $100, but that's simply not the case. $70 for the software. $30 for the sound card. Shakers are about $40 each. And an amp will be $100 to $300. It adds up quick!
If I were starting from scratch, there's no way I would have done it. But since I already have the shakers (bought them years ago), I figured I might as well make the most of them. And running them off telemetry data is worlds better than just game audio.
In for a penny, in for a pound.
