Until recently, it didn’t make much sense for us to introduce concurrency technology as most players were playing on computers with dual-core processors. Well we’re already using the full capabilities of both cores in this case.
But, over the last few years, there’s been a noticeable shift in the number of players with 4- or 6-core CPUs and this increase shows no sign of slowing down. Currently, 60% of our player base have PCs with quad-core processors.
After careful analysis of the statistics, we realized that it was finally time to add an important technological feature to World of Tanks–full concurrent rendering support, developed in collaboration with Intel. To do this, we needed to “teach” the engine to perform calculations not in turn, but simultaneously on all available cores.
