Anyone having HDD usage up to 99%?

[_]

Bought Substance designer 6 today and tried to use it on win10 pro 64 bits, but when opening task manager i see it is using HDD up to 100% and stays between 98-100% which i doubt is normal. Anyone having the same issue? :c

99% isn't a standard, measurable quantity of disk space :P

99% for 1 user is 4% for another

I've neither Windows 10 or SD6 (yet) but I'm sure a program like SD6 needs space to cache and work too like any other media editing tools. If it can tell you a percent of disk space being used per process, it should be able to tell you an actual quantity too - it might not be all that peculiar what you are seeing and if it is a bug Allegorithmic won't be able to catch it without more details (what you did that might've bloated the disk cache or something).

My pc specs are:

Win10 pro 64 bits build 1511
3770k
gtx 660 ti sc 2Gb EVGA
nvidia driver
378.66

2TB HDD 7200pm
16 Gb RAM
P8z88-M Pro Asus Motherboard

After watching the task manager for some minutes, the max hdd usage from just substance designer was just 80-83%, for 7-15 mins, and then went 0-3 %.

After that"avast Service(32 bits)Avast Antivirus"
began to use hdd up to 95% for about 5-7 mins, and later on the HDD use went to max 5-10%

This was with avast shields off.

Avast program version
12.3.2280

I guess it's similar to the HDD usage win10 does when it is turned on.

So, are you saying SD6 is using ~1.6TB of your HDD (80% of 2TB) or 80% of your disk i/o - I'm assuming it's the latter which has little to do with the size of your HDD, but again I don't have Win 10 so I don't actually know how Task Manager works there.

Judging from how it's fluctuating so much, my guess is Win 10 is just relaying to you how much of the disk i/o (read/write) is responsible by which processes - and when SD6 is running, it's using the disk the most at that time.

80% of disk i/o :)

Win10 and newest software need more and more disk i/o and actually Win10 is not friendly to HDD,I think you need a SSD.

Yup, for some reason someone at microsoft thought that it would be a great idea to ♥♥♥♥ over hdd users with win10. It's most certainly not a problem with SD6, but with Win10 (I don't own SD6 myself, but I am running win10 on my hdd and I keep getting the same 100% usage thing. ).
There are a some threads on the internet about possible workarounds, but sadly there isn't a go-to solution for this problem (apart from installing win10 on a ssd, which is not acceptable to be called "solution")

Your problem is caused by your Anti-Virus. Its not the fault of Windows or Substance, it is the fault of the AntiVirus.
These days most AntiVirus are more of a hazzard then a good thing, especially 3rd party once (that even open up aditional security risks in browsers and such --> some Firefox developers have a nice Article about that).

But what happens most likley to you, is that your AntiVirus keeps overscaning Data Substance Designer needs. So try to use it without your AntiVirus and if that makes things better, get a better one (or just use the default Windows one, it is good enough).

Besids that: Working with Textures profits extremly from SSDs, the higher the resolution you work with, the more profit you get from SSDs.

Thanks guys :).
