Video Card RAM Issue

I recently had a new desktop built. My video card is a Nvidia GTX 1070. It is an 8GB card. when I look at my message log it says I only have 4GB of ram.

 

            OpenGL Vendor: NVIDIA Corporation

            OpenGL Renderer: GeForce GTX 1070/PCIe/SSE2

            OpenGL Version: 3.3.0 NVIDIA 384.76

            OpenGL VRam: 4095

            OpenGL GPU Count: 1

            OpenGL GPU VRam: 4095

            OpenGL GPU Driver Name: nvoglv64

            OpenGL GPU Driver Date: 6-27-2017

            OpenGL GPU Driver Version: 22.21.13.8476

            OpenGL GPU Model: NVIDIA GeForce GTX 1070

            OpenGL GPU Device Path: pci\ven_10de&dev_1b81

Here is my system.

 

Windows 10 Pro

Intel Core i7-6900K

Nvidia GTX 1070

Crucial MX300 275GB SSD

Crucial 4X4GB DDR4 2400 RAM

 

Anyone have a similar issue? I have Chief X8 and X9 on this system. The message log in both programs say the same thing. If anyone is running Windows 10 Pro with an 8GB card can they have a look at their message log and tell me if you are getting a similar message? This could just be a logging issue.

My Message Log.txt reads the same as yours except you have a newer driver.

 

Not quite sure where you do CTRL+F from but Nvidia and Windows read it as 8192MB but I did see another program recently that read it also as 4GB and I was surprised at the time but now I can't remember what software it was.  It does seem to be a known issue that chief does not report it properly.

I think it is just reporting incorrectly from what I recall from previous discussions but I think it should be an easy fix for Chief that would prevent a lot of questions.  If anyone has evidence otherwise or can confirm this it would be much appreciated.

I believe what you are seeing is the amount of video card memory Open GL has set aside for it's use. Keep in mind that each running program, depending upon the total amount of available memory, will block out a certain amount of memory for it's exclusive use. Your video card has to service more than just CA, all of your other running programs are also using the video card and as such they also need memory. Things will be faster if they are not over writing each others data so they divide this up. I would not be concerned with this, it's normal. Download GPUz and it will tell you how much video card memory is actually in use. I think you will be surprised at how little of your 8 GB is actual being used.

I have two other machines the vRAM in the message log for both of those machines displays the same RAM value of the card. My notebook has 2GB message log says 2GB, My older desktop has 4GB message log says 4GB. I am just trying to figure out If there is a problem with Windows 10 ability to use 8GB or CA to use 8GB, or if there is a problem with my desktop. Based on Chopsaw's response it would appear it is either W10 or CA. If I have time I will pull the 8GB card and put it in my older machine that is running W7, although I think I read somewhere that W7 was only capable of using 4GB of video card RAM.

Download GPUz, that's the program that is used by just about every graphics card tester. It will tell you what is really happening. The difference you are seeing may be due to the fact that Open GL will allocate whatever it can up to 4GB, it could be that for Open Gl it is unlikely to need more than that. As I said, you will likely be suprised at how little video card memory is actually be used. Also, allocate memory is differfent from actual memory used. Actual memory being used is what really determines functionality, problems will only arise when actual exceeds allocated.

      How to change NVIDIA Optimus graphics settings
       
      July 2021.
      Windows 10 also has it own settings now and Chief has now made a KB article about how to set that up too.
       
      https://www.chiefarchitect.com/support/article/KB-03140/forcing-chief-architect-programs-to-use-a-specific-graphics-card-in-windows-10.html
       
      Dec. 2020 :  Window's 10 also now has a some built in control of what graphics processor is used but this is my preferred method....

      It maybe worth updating your Intel Drivers ( download the Intel Driver and Support Assistant )  as well but in general
      this is an issue of the Nvidia (NV) Discrete Graphics Card not being used by Chief in your Laptop , and some Desktops.
       
      Many laptops ( and some Desktops ) come with both an Intel UHD Graphics Card and a Discrete Videocard Card
      eg a Nvidia Geforce GTX or RTX  (or AMD Radeon), which is the Card, Chief should be using especially in 3D Windows.
       
      The Issue lies in that Chief is not "seen" as a 3D Game by Nvidia's Driver,(NV), so the switch may not always happen automatically,
      so we need to ADD Chief to the Nvidia Control Panel 3D Manage Page , and set the Nvidia card to be always used when Chief is Open
      ie: make it the  "Preferred Graphics Processor" ,            this will likely need resetting EACH time the Driver is updated.....
       
                                                        Desktop NV CP  1                                                                                        Desktop NV CP  2  
                                                ( Chief already added to list )                                                                        How to add Chief to the "List"
       
               
       
       
      General Laptop "everything uses" NV Card Setting                                                              Laptop Chief NV CP Settings
      ( I recommend this  only if plugged in to AC ) 
       
               
       
                              This mode will use a lot of your battery quickly                           Once set don't forget to set the Options ie No# 7 and 8 above in Desktop pic 2 too.

      I know many of us are unable to get the latest video card, which we will need for CA13.  Meanwhile, I do not even bother to ray trace because it's so hit or miss if I selected the right settings for a good result. And I don't know the result until after a 20-60 minute rendering.  When I am doing several views for a client, this is way too time consuming. If we still can't get the latest video card upgrades when CA13 comes out, what do we do?  Is there any way that a software developer like CA has an industry advantage to make sure its customers have access to necessary components?

      I was wondering if anyone in the forum can recommend what upgrades I can use to allow me to have Chief Architect run smoother. I am an interior design student and my PC does an 6/10 job when it comes to viewing spaces in 3D, especially when the space starts to become around 2,000 square feet. 
       
      I currently am using an HP Pavilion All-in-One - 24-r114 PC. It has an Intel(R) Core (TM) i5-8400T CPU @ 1.70GHz - Installed RAM 12GB. Graphics Card Integrated Intel UHD Graphics & 2TB storage (around 1.7TB storage still available)
       
      I am no tech-geek and have not upgraded anything on this pc. I really do not understand what RAM is or even the graphics card. Instead of purchasing a gaming-type PC to assist with the rendering, I am wondering what alternatives I have that may allow my all-in-one PC to run much smoother with large scale renderings. Thank you!

      Hi, just wondering if anyone else is seeing the disappearing Icon in the Drawing Area with the latest Nvidia Driver in X11, it has happen twice today already,so I may need to go back to the 436 Series Driver which I had no issues with.
       
      This was also an Issue with X11 back with the 388-396 Series Drivers when 382.05 was the best driver to go back too but I have not seen it since 400 Series Driver came out.

      This isn't really Chief software related, so this thread might belong in the Chat section, but...
       
      The new Ray Tracing Video cards from Nvidia, the Geforce RTX 2080 Ti, is failing for lots of users. And the replacements sent from Nvidia are failing too. It's affecting some of the 3rd party cards too.
