One can evaluate with about anything as long as you still have PD18 available.
For a very basic test that could even be replicated by CL perhaps, I took the 3 skateboard files, Skateboard01.mp4, 02, and 03 and duplicated in the timeline 5 times to create some working footage. I then produced this to a AVC MP4, default 1920x1080/60p 40Mbps profile, again just to create some higher complexity working footage with reasonable decode load with the canned source files.
1) place sport 01.jpg in the timeline (needed because of another continued PD anomaly/bug)
2) place produced footage above in timeline (see timeline pic)
3) produce to same profile for simplicity with various decode and encode device options but not utilizing SVRT, we want to actually encode the timeline
4) do the same with PD18 and PD19
Results shown in attached table. Basically, for this simple transcode case, anytime the CPU is used for decoding, PD19 is nearly 1.5X slower encoding than PD18. Results will vary based on hardware but PD19 a significant step backward on encode performance when CPU needs to do the decode tasks which is often needed to prevent other anomalies often shown in prior versions.
So what often is referenced as the staple, CPU decode and encode, simply got significantly slower with PD19 for the same perceived quality.

I just wanted to follow-up that the issue I was seeing of PD19 being ~1.5X slower than PD18 for CPU decode/encode has been resolved. I now see nearly unity ratios for PD19/PD18 for all render configurations. For some reason the Virus Protection software I use had an anomaly with PD19. It had no such issue with PD18, 17, 16. In fact, after resolution, the PD18 encode times are identical, it only reduced PD19 encode times.
