Hi Developers,

Hi There,

After using this version for a while I find a interesting bug problem, compare to Octane 3.06 and the 4.05 there is a clear slowdown on the sampling at 3.06 I have "25ms/sec" I have in 10 seconds close to "400s/px" and at 4.05 I have "0.020ms/sec" sometimes lower like "0.01ms/sec" and get "1s/px" after 25 seconds which is crazy slow after one minute I still get 4 samples, I also tried on 2019XB2 for test is compiling the scenes really slow but the samples is better getting more close to the "25ms/sec" of the 3.06 but freezes at begging and after is getting unstable sampling, between "0.020ms/sec" to "10ms/sec".

I tested same scene with a 1080ti windows 10, also with sets on windows 7 and different GPU 700's and 900's series same results.

I could share the scene but I need on private for security and private reasons.

Please let me know.

Could guys tell me if there something I should check on the scenes?

Hi Guys,

After further test I find the bug is based on instances type I upload the scene on this link here :

https://render.otoy.com/forum/viewtopic.php?f=33&t=71853&p=365558#p365558

Look design is the same between 3.06.4 to 4.05 only new 2000's version is looking different shader side but here 4.05 has a trouble to recognize a particular type of instance recognized before at 3.06.4
Please also pay a close attention on memory usage at the same scene? 3.06 uses close to 285mb, 4.05 uses 495mb and 2019RC1 uses 616mb
