Intel i7 4790K Performance Test using iRacing & Assetto Corsa
Intel i7 870 vs i74790k





This is good stuff. Very informative and hopefully helpful to those who are racing one or both of these awesome sims.  How to get the most performance with a few tweaks of settings. Do you really need to upgrade to a better CPU or can a graphics card do the trick?


Betta Lines built his system using a new nVidia GTX 980 4Gb graphics card, but when he fitted the new card he was using his older Intel i7 850 CPU. The i7 850 processor was still performing well with newer Sim Racing titles Assetto Corsa, but he noticed that there were hardly any improvements when using the same system for iRacing.

After a lot of testing, it became apparent to him that the older CPU was holding back fps/ performance in iRacing. iRacing is still using the  DirectX 9 technology(can someone verify?), while Assetto Corsa uses newer DX 11.
He decided to swapped the Intel i7 870 for a newer Intel i7 4790K to find out if this would increase performance in iRacing where he was losing a lot of fps in certain areas.

In the video the Intel i7 4790K (not overclocked but set at out of box 4.2 GHz) improved the performance quite impressively.  He also performed a test with Assetto Corsa to point out that with a newer CPU you’re unlikely to see big improvements in games  already running DX11 technology.
