Solidworks 2019 Speed Enhancements

There are many SOLIDWORKS 2019 speed enhancements, but the most noteworthy is that a 26x speed increase in complex part viewport rotation, measured in frames per second (FPS); specifically, SOLIDWORKS 2018 tested at 4.9 FPS, whereas SOLIDWORKS 2019 tested at 129 FPS!

In this test by Alin Vargatu and Alen Topic, performance was achieved using an nVIDIA Quadro P4000 card, in OpenGL with RealView and Shadows off. For other settings on the nVIDIA card (Shadows On, RealView on, etc.), the improvements were still 23+ times faster than in SOLIDWORKS 2018, and if we look at the same settings for the AMD Radeon Pro WX 7100 card, again SOLIDWORKS 2019 boasted between 13 and 17 times faster viewport rotation results as compared to SOLIDWORKS 2018.

What could be the reason for these speed increases? Besides an ongoing code rewrite which began in 2015 and continues today, the Graphics R&D team at SOLIDWORKS has been working with graphics providers nVIDIA and AMD to take advantage of techniques developed primarily from optimizing for video game performance.

Overall, three tests were performed comparing SOLIDWORKS 2019 to SOLIDWORKS 2018, using both video cards. These tests included the SOLIDWORKS Performance Test, a Large Assembly Graphics Performance test, and Complex Part Performance Test. The Large Assembly Graphics and the Complex Part Performance tests specifically looked at viewport rotation performance.

To see the performance of SOLIDWORKS 2019 side-by-side against SOLIDWORKS 2018, check out this video. SOLIDWORKS 2019 gives you zoom, rotate and pan performance for large assemblies similar to what you’d expect with Large Assembly mode turned on, but without the graphics quality loss associated with Large Assembly Mode.

In fact, in this CATI test, a 4500-part assembly in SOLIDWORKS 2018 rotated at 17 FPS with Large Assembly Mode turned on, but when the same assembly was rotated in SOLIDWORKS 2019, it rotated at 26 FPS, with Large Assembly Mode turned off!

Alin & Alen ran quite an exhaustive test comparing SOLIDWORKS 2018 to 2019, using a test machine that sported an AMD Radeon Pro WX7100 vs the nVIDIA Quadro P4000, in the areas of graphics, rendering and RealView, using large assemblies, complex parts and more.

Some users have tried to reproduce these results and have run into minor bugs that will likely be fixed in SP1 – until then, to learn the workarounds, check out this thread on the SOLIDWORKS forum.
