is this UI sluggishness normal?

[shortcirkuit]

Hi guys

thought i would do a quick video - is this normal?  sometimes its zippy, 90% of the time it isnt.  Scenes re not too big.
my system is a ryzen 5995xw with 256 gb ram + rtx 4090.

are you guys experiencing this?

I feel when i restart pc it works fine for a little while and then this sluggishness holds me down.  It wastes SO MUCH time.  I dont know if max, corona or windows or a combination of.

Yeah sluggish Max Editor (but also other Max UI) has been my bane for like forever. I've no idea what influences it either, but Corona Materials are more suspectable to it than for example MaxPhysicalMaterial which is instantaneous. And big PCs, Threadrippers esp. even further.

There are host of things that can (potentially only and often in specific circumstances) help:

- running High Performance or better, Ultimate Performance power plan.
- turning off almost every real-time protection, esp. Control Flow Guard. Or at minimum, making exception for 3dsMax.exe.
- yes it seems bizarre and I haven't done it in past either, but restarting 3dsMax and Windows itself from time to time.
- Turning sufficient amount of cores in Corona Setting off for IR. But I have tried turning off half the cores and the benefits are often less than ideal.
- This will cost performance even more, but I am running Threadrippers without SMT (Hyperthreading). From 128 Threads to 64 Threads is roughly 25perc. loss of multi-threaded rendering performance. But in my case, it does make almost every 3ds Max related performance better.

But yeah, outside of that, it's a mystery to me. As you say, ENDLESS waste of time.

I am not sure if the issue is getting worse, or just everything else is getting better and this sticks up like sore thumb.
Maybe we're just used to our smooth smart phones..

im glad im not the only one.... surely Corona devs could potentially look into this?  Its a major bottle neck which hinders the creative process as it introduces frustration from a technical point of view.  It may well be a max thing, but as you said the maxphysical material works instantaneously.  Its been over 10 years and i still find myself doing things like restarting/ removing animation layers, cleaning the scene and in extreme times reinstalling max and at worst, formatting the pc lol.... which isnt a bad thing from time to time.....

thanks for the tips - i also stumbled across what they call the QT TRICK - have you heard of this?  refer to this link:

i havent noticed a different (maybe im doing it wrong) - have a go and let me know if it works for you.

PS - i also noticed the latest windows update, the right click context menu appears to be slower with my UI crap - theyre not helping either!
