Hello, last update I updated the renderer to be multithreaded, which may have issues with servers that have a lot of cores, since the multithread overhead may be more expensive than using a single thread. However, this update aims to fix that by adding some options to the config that should let you fine tune the renderer's performance:
By default it's set to use multithreading, and use 4 threads for the thread pool. You can disable multithreading if you'd like as well. Thanks, and please be sure to report any bugs asap!
