The Quadro FX 4800 graphics card is manufactured predominately for those needing cards for their workstations rather than for gaming. It's one of the more powerful graphics cards NVIDIA released from this series.

The PNY NVIDIA Quadro FX 4800 for Apple Mac or Mac Pro is an ultra-high-end graphics solution that's designed to meet your workstation needs. Luckily, NVIDIA has the solution to that problem.

But there is no practical need for that as there is a tiny amount of peculiar Windows applications that could utilize two cards (because it is much more complicated process than SLI/Crossfire).When your Mac or PC has a lot of processing power, you need a graphics solution that can keep up with it. In theory, we could map both video cards to the guest OS and somehow allow applications to use it. Since Parallels video card is virtual and relatively high-level (we do not work with hardware directly, but via API or OpenGL instead), it is not possible to effectively split tasks between two video cards, as we are not emulating SLI/Crossfire. It is up to these applications to somehow split tasks between two cards, or just use one instead. That is why macOS applications consider two video cards working in tandem as two separate video cards.

That basically means that macOS and its drivers can be considered as one -they cannot be split.
Contrary to Windows where drivers belong to vendors, Mac drivers belong to Apple (even though they're developed in collaboration with vendors) and features are controlled by Apple as well. This is the reason why macOS is not supporting Crossfire, nor the SLI.
Only it has the required data regarding technical specifications.Īpple uses its own video driver for macOS. However, the main point is still there: it is the driver’s work to split tasks between video cards, as only the driver can optimize input data for video cards and synchronize cards' work. It is explained more precisely in specific guidelines for developers. Some tasks may be split more efficiently than others. That way, applications keep using standard API (OpenGL or DirectX) and the driver splits tasks between two physical video cards. The main purpose of Crossfire (by ATI/AMD) and SLI (by NVIDIA) technologies is to unify a pair of 3D accelerators for increased performance. NOTE: Starting from Parallels Desktop 15, 3D acceleration is enabled by default in Windows virtual machines. A special checkbox in configuration of Windows virtual machines allowed you to disable or change the level of 3D acceleration in Windows has been removed due to very low usage of the feature. To make sure this option is enabled go to virtual machine configuration window > Hardware > Graphics > Advanced Settings Note: Parallels Desktop does not control when to switch between graphics cards. To learn more about the feature, please visit the Apple's KB HT202043. If your Mac has discrete graphics, Parallels Desktop can use the macOS "Automatic graphics switching" for its virtual machine(s). It provides a more economical alternative to the standalone card, known as "discrete graphics" or "dedicated graphics." In this case, Parallels Desktop will use the resources of the built-in Mac built-in graphics. Most Mac computers have an integrated graphics card, which is built into the motherboard and shares memory with the CPU. The actual acceleration is achieved by translating Direct X commands from the guest OS to the OpenGL API on the macOS side. Instead, Parallels Display Adapter driver (which is part of the Parallels Tools installation) interfaces with virtual hardware and provides 3D acceleration features. Parallels Desktop has no access to the Mac's device's physical graphics cards.
