Benchmark Details

Core i7 860 with 8 GB of RAM; GeForce GTX 660; SSD; Windows 7 x64.

Programs were run thrice; the best numbers were recorded.

Loading time begins with launching the program with the file as parameter, and ends with the first UI response to user input.

Memory demand is the peak working set during loading time.

One second has been subtracted from MeshLab’s loading time for manually closing the remove duplicate vertices prompt.

MeshBrowser’s loading time begins with opening the file instead of launching the program.

Compatible

Papa’s Best STL Viewer opens countless STL variations, even where other programs fail:
