[HELP] perf. RTX 3060 ti slower than GTX 1070 - NVEnc
#40
Quote:in my opinion, the optimal preset to use with NVEnc and RTX 3060 is P3.
Following your data and since ".. P1, P2 and P3 are essentially the same .." you could also say that P1 is optimal for you. Tongue

As a side notes:
  • I hope you are aware that if you did your testings only for one sample it's probably only true for that sample. Wink
  • Both psrn and ssim doen't always align with human perception.

Quote: As it is possible to see the presets P1, P2 and P3 are essentially the same since the BitRate, SSIM and PSNR are equal. Starting from the preset P4 (default) the speed, BitRate, SSIM and PSNR start to decrease. But while there is a significant drop in speed between P4 and P7 (quality) there is a little impact on the quality metrics SSIM and PSNR.
Your numbers do not really show that. SSIM changes by 0.0001 points, PSRN changes by 0.069, Q_SSIM changes by 0.16%, W_PSNR changes by 0.4%, that all seems rather minial changes.
