Simulators are still very highly single-threaded performance-bound. Particularly flight simulators.
- mikepurvis 8y agoThat's surprising to me; wouldn't they be able to represent huge chunks of world state as giant matrices, upon which operations are trivial to parallelize?
- Alupis 8y agoYes, but most flight sims are based on very old codebases. X-Plane has started to change, and Prepar3d too, but I imagine they're so complicated it's difficult to just do without breaking a lot of things. For the time being, even with latest versions, single-threaded cpu performance is the largest concern in these sims.
