LuxMark is an OpenCL cross-platform benchmark that allows us to check the performance of the CPU and graphics card and compare results on different operating systems. Interestingly, LuxMark allows you to test the GPU and CPU together or separately. It is worth mentioning that the originator of this programme is Jean-Francois 'Jromang' Romang, who in 2009 prepared this tool to promote LuxCoreRender. Now, however, it is a fully independent and also the most popular and most frequently used benchmark of this type. LuxMark provides several scenes of varying degrees of complexity for different benchmarks and load tests. The whole thing boasts a simple, easy to use user interface.
