Fly the Maddog X SP1 and Prepar3d v 4.4: development update

Recommended Posts

We want to share with you the progress of the development.

At the moment, we are working on the MD-83 & MD-88 variants which have entered an advanced beta testing stage; meanwhile, we are finalizing the 'advanced icing' feature that will be part of both the 'variants' and the 'base' MD-82, with an update to SP1 that will be available at the same time of the MD-83 & MD-88 release. The upcoming SP1 update will be a small autoinstaller, obviously you'll need the SP1b335 version first on your system.

As you know, we are also dealing with the PBR LM introduced with the new P3D v4.4, and we are working full steam to include those new models in the -83/-88 release (and the -82 update). We have taken the decision to give you the option, in the Load Manager, to choose between PBR or NON-PBR models.

Talking about PBR, we'd like to answer to a couple of questions we have received.

Do you use dynamic reflections in the preview pictures or not?
Yes. We've been doing some performance testing today on the external model, and you can check the results below. Setting of 'Dynamic Reflections' in P3D options ranges from Off to Ultra, and this affects the quality vs frame penalty ratio of the dynamic rendering, being Off = no PBR (no FPS loss) and Ultra = best visual experience (worst FPS loss).

I assume that current (customer) liveries have to be reworked in a way to work with PBR?
Generally speaking, not for the graphic content of the textures files: the only needed change will be the naming of the texture files to match the new model, and this will be automatically handled by the 'Liveries Manager' if you use the automatic livery packs; if manually adding repaints, a simple batch file will perform the needed changes for you. Most of the current repaints already look pretty good with the PBR model; bare metal liveries, as you may imagine, require a different approach instead, to get the most of the new visual engine. 

The 4.4 PBR effect looks really nice. Is there any performance penalty or free like bump mapping?
The implementation of the PBR in P3D v4.4 with compliant models does not result in a significant loss in terms of performance, compared to the 'old' Dynamic Reflections, actually it's even a bit better.

We run some tests. Reference PC is an I7 7700K @4.20Ghz (OC @4.50) with 16Gb DDR4 and 1070Ti.

P3D v4.4 @ 2K resolution. Add-ons: ORBX FTX Global + EU LC + Trees, ActiveSky + ASCA + Envtex + custom PTA profile.
