If it’s a desktop, you can buy a dedicated video card and put it in… maybe. If it’s a laptop, I don’t think you can do much. Whether you can actually add a video card to your desktop depends on I guess the machine and the type/number of accessory slots available. You also need to make sure your power supply can handle the load. Sometimes it’s just better to buy a newer, higher performance machine.
Everyone needs to understand for once and for all…
INTEL HD VIDEO IS NOT, HAS NEVER BEEN AND LIKELY WILL NEVER BE GOOD FOR RHINO. (or any 3d modeling software for that matter)
Your intel has 1gb vram… our min spec is 4gb vram.
Even with the newest drivers You will continue to have performance issues with this set up trying to do professional work.
STANDALONE VIDEO CARDS PEOPLE>>STANDALONE VIDEO CARDS!!!
According to Task Manager and NVIDIA screenshots (shown below) my laptop has 2GB of dedicated video RAM and 15.8GB of shared video RAM. If this enough video RAM for Rhino 6 and 7?
Are you saying that shared video RAM is completely useless, or that it may be too slow for professional use? Is there any way to test the speed of both kinds of RAM?
Computers can have either a dedicated graphics card with on-board dedicated memory (RAM) or an integrated (shared) system where the graphics components are part of the processor (CPU). An integrated system uses a portion of the system memory for graphics, which decreases the amount of RAM available for general use. Another option has been added to the market, computers with both a dedicated graphics card and a shared system. This is called switchable graphics or APU by some manufacturers. The computer can be configured to either choose on the fly which method works best for the current application or the user can choose manually which system to use… Shared systems were traditionally put into lower-end computers… In the last ten years, however, shared graphics systems have improved greatly. source: https://www.crucial.com/articles/about-graphic-design/dedicated-graphics-card-vs-shared-cpu
Intel graphics just do not work well. and haven’t for a decade now. There used to be an open gl option in rhino just to make these card work at all (use accelerated hardware= off) with v6 forward it’s hidden in the advanced options, but even with that…they will always be barely functional.
You need a stand alone card to do professional work.
Mostly it’s that it’s simply not enough. All the added OpenGL features Rhino 6 is using mean more stuff needs to be stored in VRAM. Textures, buffers, caches, polygons.
I think the 8GB per monitor recommendation is a bit…extreme, maybe for 2 4K montiors I suppose, but 2GB is definitely inadequate. 1 GB was a lot when I bought a high-end “gaming” card for Rhino in 2009 and that’s not actually enough to run modern GAMES. My current video card has 11GB, and the next will have 12 or 16 or 24.
I use Nvida GPU, not Intel GPU. Take a look at the second screenshot in my latest post. It says that Nvidia GPU uses 18GB of RAM (2GB dedicated and 16GB shared). I have connected 4K monitor to my laptop and I display 4K videos at 60Hz frame rate without glitches.
Both my laptop and desktop only have 2 GB of VRAM. I haven’t had any display problems with Rhino. What am I missing? :Perhaps it is because I do very little rendering and my models are generally not too complex.:
Yes, I have posted similar findings in other threads. I think the minimum recommendations McNeel has set are too high personally. I have an old laptop with 2Gb that is used occasionally by students in my class and it works fine for what we have to do. Here I have a 6Gb card that runs two HD monitors and a laptop with a 4Gb card that runs a 4K screen. So personally I feel that the ‘minimum’ recommendations (4Gb for a std HD screen and 8Gb for a 4K screen) are set at least 2x too high. I would like to hear some real explanations for those numbers with practical use cases to show they are justified.
