By Eric C (RL) - 4 Years Ago Iray v1.4 - Performance Enhancement  Announcing the update for Iray v1.4: Enhanced: Support for MDL 1.5, please visit nVIDIA website for more information. Enhanced: Update Iray SDK to RTX 2019.1.5. This will improve render speed from  0 - 106% performance increase according to the MDL versions used. See the two benchmark tests for Iray render speed comparison below. By Eric C (RL) - 4 Years Ago #Test 1  Hardware spec: CPU: i7-7700 Memory: 16G RAM Graphic Card: GTX 1070 / 8G Project: IC Embedded Project - Loft scene & Iray Export Settings  When using Iray 1.3 ( IC 7.7)  and set the render time as 3,600 seconds, we get 486 iterations: When using Iray 1.4 ( IC 7.7)  and set the render time as 3,600 seconds, we get 593 iterations: As a result, the project has improved render speed of 22%. #Test 2  Hardware spec: CPU: i7-9750 Graphic Card: Quadro RTX 5000 / 16G Memory: 64G RAM Project: IC Embedded Project - Roma scene   When using Iray 1.3 ( IC 7.7)  and set the render time as 1,169 seconds, we get 1,000 iterations: When using Iray 1.4 ( IC 7.7)  and set the render time as 565 seconds, we get 1,000 iterations: As a result, the project has improved render speed of a whopping 106%!!!! By Geoffrey James - 4 Years Ago Just for the heck of it I ran the Loft Scene benchmark, as defined above, on my dual RTX Titans. It did 1,000 passes in 763 seconds using the most recent version of the iRay renderer. I must be doing something wrong. Any suggestions?
