Multicore

[Trips]

Hi,

I'm running the latest release version of L3DT Professional (2.9) and am generating a 131,072 × 131,072 heightmap.

I noticed during both the Design Map and Height Map generation that my 4-core i7 (Win 7 64) only seems to be taxed to 25% (single core) for almost all of the calculation time. Do I somehow need to enable multicore support?

Settings / Multithread settings shows Enable multithreading checked and shows the correct core count. Utilities / throttle CPU is not checked.

Thanks!

Hi Trips,

Multicore support is not provided for all calculations yet. The most CPU-intensive calculations have been multithreaded, including:

• Texture map.
• Light map.
• Normal map.

The next calculations to be multithreaded are (probably):

• Attributes map.
• Fluvial erosion.

Fluvial erosion is the slowest part of the design map and heightfield generation, so when it is multithreaded the speed of these two calculations will improve markedly.

Cheers,
Aaron.
