The replies seem to heavily conflict with Ralf’s reply in this thread:
geometry 3d CPU impact
“CPU performance is also affected since for one vorpX has to do more work and also many calls to the DiretX API are doubled, which can be quite costly CPU wise. High single thread performance is what’s most important here. If it doesn’t blow your budget, I would recommend to go for a quad core i7. High single thread performance combined with the i7’s HyperThreading for 8 virtual threads is probably the best you can get for vorpX (and gaming in general).” – Ralf
