Hey,

Could some one please highlight various features of p3d v3.2 that separately or in combo tax the cpu , gpu .

Kind regards

When your mouse pointer is over a P3D item (e.g. a graphics item / slider) you will get a little pop-up telling you if it will tax systems performance. Then you move the slider and test the result on your system. Do the tests, one at a time, for every setting in P3D.

There have been a number of in-depth posts on this topic so you might try searching through old posts. Anything that shows up on screen uses some GPU and CPU cycles. Being CPU or GPU bound can depend a lot on hardware and usage, but here are some features that tend to use more of one than the other.

Some GPU heavy features:
- Shadows (especially terrain casting, and cloud casting at certain times of day)
- Dynamic Reflection
- Ultra Water Setting (3D wave simulation)
- Volumetric Fog
- HDR
- MSAA
- Increasing the resolution of a 3D view
- Particle Simulation and Rendering (especially if particles are near camera and take up a lot of screen space)
- Cloud rendering (if clouds are close to camera and filling the screen)
- Terrain rendering when tessellation is enabled

CPU feature:
- Gauge and panel rendering and GPS maps.
- Air and Ground Traffic
- Opening up multiple 3D views
- Terrain rendering when tessellation is disabled.
