My R21 viewport is slower than R20


#1

Hi.

I work a lot with heavy CAD models and I find R21 is slower at selecting polygons and executing commends like select connected.
At first I thought it might be the CAD importer so a created a test scene in both R20 and R21 where I added 27 cubes with 100 segments on all sides and then connected them all to make one object.
R21 is painfully slow and for me is unworkable.

I installed multiple nvidia drivers but no luck.

Anyone else having this issue?

System
Windows 10 - 1903
Core i9-7980XE overclocked to 4.2GHz
128GB Ram
RTX 2060 for display and 2x 2080Ti’s for rendering

I get the same here, geforce 1080ti 436.30 drivers


#3

I sent a test scene and a screen recording of the Issue to Maxon.
It’s been added as a possible bug.

Attached screen recording below. R20 first and then R21.

same here… dynamics played great on c4d 17 but if I openen it on c4d21 it hangs. and yess they been cached bake nothing improves… offcourse maxon tech in a really nica way told me it was my HARDWARE fault… need to upgrate… jaja funny.

and now… just found out… CV-TOKENS are not working on r21…


#5

Mash,

are you running into the same problem (for me it was fine on macOS), or do you get the same behaviour in R20 & R21?

Best

Baking dynamics in C4D has always been a waste of time for improved viewport playback.

It’s not until you step outside the Maxon BS bubble and use other software that you realise just how bad C4D artists have it. By any chance did that Maxon tech suggest you buy a good single threaded CPU on the cusp of the year 2020?

Maxon can make a 32 core beast of a CPU feel like a 4 core from a decade ago an impressive feat by any measure.

32 core? almost… I am sitting on a 64 core workstation 3 years old. actually I been outsourcing lots of work to other softwares like booleans or geometry always can trust MOI fast simple and powerfulll… render systems… whay to many to be named… but I think your rigth… need to find a good simple dynamic software to add to the tool box.

My advice would be to take a long hard look at Houdini, it’ll make use of 64 threads and once your scene is cached unless it is absolutely massive it’ll playback in real time. Learning Houdini is one of the biggest investments in your business you can ever do. Your grand children will be nearing retirement age before Maxon sort C4D’s abysmal performance out.

I used to regularly export an Alembic from C4D to Houdini just so I could see the scene playback in real time not at 2-3 fps like C4D could muster. Download the Apprentice version of Houdini and give it a test. If you have an XParticles scene chugging in C4D export it as a Houdini BGEO and watch it at the full fps.

Maxon are very fortunate that there are a lot of myopic people willing to keep buying into that C4D is a great Mograph tool.

There is interesting, if residents of Aixsponza had such thoughts and turn off from c4d… to houdini


#10

will do. thanks for the heads up. and what about blender? have tyou try blender? has some nasty goods inside.


#11

He hate blender, please, do not remind about it :sunglasses:


#12

This kind of issue raises questions about beta testing quality.


#13

Just did some more tests, there’s no speed difference between R20 and R21 with the same settings. The only difference between 20 and 21 is accounted for by the quadrupled viewport resolution because of R21’s 4k support.

If you need to pull a bit of performance back, getting rid of object highlighting and outlines can be significant for all versions of c4d


#14

The C4D beta testers are more interested in capitalising on their early access so they can coin it in with Youtube videos and training courses than properly testing C4D.

It doesn’t surprise me C4D is getting slower the creaking architecture can’t take modern workflows, instead of writing a new core which was released with R16 Maxon should’ve just written C4D from the ground up. Years of not investing in rewriting C4D sooner is catching up with them.


#15

I can’t recommend Blender to someone who has just bought R21 that would be deeply uncool. Anyway they don’t like us talking about Blender round these parts, they get a bit touchy and start flagging threads. Very sensitive folk on this forum.

I actually haven’t replied to another thread because I know the answer to the problem is to use Blender and I don’t want to be seen as pushing Blender.


#16

that‘s probably why you‘ve seen hundreds of r21 vids on youtube when it came out :wink: … or r21 specific training material.


#17

Yeah, R21 is not really a great example because so poor was this update only a couple of ‘influencers’ could be arsed to make a launch video.

I’m surprised that not one influencer could be bothered to make a video about the new ‘enhanced’ splash screen. A missed opportunity for sure.


#18

I turn off it. I do not get why need it. If wil be closer to project management, i want to back Biomekk’s OLX (Budget too)


#19

no offense but a beta tester is not the same as YouTube influencer with NO knowledge in REAL WORLD projects… facts? for each youtuber go and hunt down there portfolio… not even 1 ONE real world budget project…

to become beta tester for many of the software house… knowledge of the software is not enough. you need to have real world experiences on workflows and pipe lines… I haven’t seen the first production or design house that uses PLUGINS… or KITS… or maybe I am just to old…

another option: let me know your comments on this… so putting all the eggs in one basket its a bad idea… like me I depend on cinema for everything. what if I get one software for each one of the steps modeling, texturing, lighting and rendering. any thoughts?


#20

No offence but I was being sarcastic about the beta testers by calling them influencers. It seems to be their main role to pretend all’s well in C4Dland.

I am one for the KISS principle, I try and keep my personal pipeline as minimal as possible. I use Houdini and the unmentionable Free 3D software for everything. These two applications have you covered for everything in your list and if you insist on using C4D will fill in all of the gaping holes of the C4D workflow of which there are many.

I have a Redshift license I use in Houdini but mostly I’m rendering with Eevee which on the current project is spitting out 4k frames in 15 secs.

With USD coming in you’ll be able to make your whole pipeline out of individual apps that best fit the job in hand but until that is a reality use Alembic, FBX and OpenVDB etc.
