Huge Upgrade for your Podium DD! Much more fidelity and faster response
When the Podium Direct Drive systems launched earlier this year, we included an improved Tuning Menu system compared to our belt-drive wheel bases. Several driver and firmware optimisations followed, along with FanaLab, which is becoming more flexible and powerful with every version.
Today, we’re introducing the first Performance Update for the Podium Series, which is available as a beta driver package (v352). This includes some major driver optimisations and firmware updates for the DD1 (including PS4 version) and DD2 wheel bases and motors.
- Reduced FFB latency by 23% - latency is the enemy of simulation, so lower latency means a general performance improvement in all aspects of force feedback.
- Increased resolution of the FFB signal to 16-bit (65536 increments) instead of 8-bit (256 increments) - this also helps with smoothness and response. The fidelity is now 256 times better!
- Improved FFB linearity - a more linear response means more consistent torque delivery across the dynamic range.
- Improved motor control with significantly less ‘loss’, to resemble the raw FFB signal more precisely. Simply described, the previous motor handling acted like a slight filter on noisy FFB but also reduced detail (1:1 game FFB can be quite rough and noisy, therefore we have added a new filter to the Tuning Menu called "Force Interpolation" - more on that below).
- Improved Spring Effect calculation to improve oscillation behaviour.
- Improved Damper Effect calculation to improve oscillation behaviour.
- Improved Natural Friction calculation to solve unwanted vibration.
New FFB Features:
- Linearity Mode “LIN” reduces maximum FFB output by a small amount to guarantee a consistent output between peaks and holding forces. Improved general linearity between game output and torque output.
- Force Interpolation “INT” (similar to the ‘Reconstruction Filter’ on OSW/SimuCube) filters and smoothens the incoming rough game FFB signal and increases the refresh rate. For example a 60Hz FFB signal (e.g. iRacing) looks like rough steps on a graph and can also feel like this, but using Force Interpolation, the signal is recreated as a smooth curve. In comparison to FEI, this filter is a lot more powerful as it doesn't influence latency as much, has a better smoothing algorithm and doesn't eliminate effects completely.
- Natural Inertia "NIN" simulates additional weight on the steering axis. This can be particularly useful when using light wheels like the P1 or McLaren GT3. It also makes the Natural Friction setting feel less ‘sticky’ on direction changes.
Other notable changes and fixes:
- All Tuning Menu parameters have been rearranged into a more logical order. Now the list starts with the settings that are constantly influencing the steering independent from the game, followed by FFB settings only influencing the game effects, then the vibration effects, and then settings dependent on connected hardware.
- Added dynamic tooltips in the Tuning Menu, which makes more effective use of the OLED, and should make Tuning Menu adjustments more intuitive and less intimidating for beginners.
There are many more improvements and fixes included in this update - a full list of changes are available in the forum.
We recommend that everyone with a Podium wheel base should try it! And because many of the optimisations are within the firmware, the Tuning Menu and motor performance improvements apply to consoles too.
