Virtual reality is a bit more intensive to run. Running two screens at high refresh rates takes some power. So you may wonder, is 6GB VRAM enough for VR?
The amount of video random access memory (VRAM) necessary for VR (virtual reality) depends on several factors, including the resolution of the headset, the complexity of the scene being rendered, and the graphics settings used.
Is 6GB VRAM enough for VR?
In general, 6 GB of VRAM is sufficient for most VR applications if you’re using a mid-range headset with resolutions around 1080p or 1440p.
On the other hand, if you’re using high-end headsets like the Valve Index which offers 1,440 by 1,600 resolution per eye, then consider investing in a graphics card with more VRAM.
VR gaming requires a significant amount of resources from the graphics card, as it must render two separate images at high frame rates to provide an immersive experience.
The resolution of the VR headset also plays an important role in determining how much VRAM is necessary; higher resolution VR headsets such as the Valve Index or the HP Reverb G2 require more VRAM than lower resolution models like the Oculus Quest 2.
The Valve Index suggests a minimum of a GTX 970 or AMD RX 480. Which have 4GB and 8GB of video memory respectively, whilst the recommended is a GTX 1070 with 8GB of memory.
VR applications, due to the complexity of the scene being rendered, can be very demanding on graphics cards. When playing a VR game with highly detailed textures, advanced lighting effects, and lots of objects onscreen, your graphics card may need more VRAM in order to keep up.
The graphics settings used in VR applications can also influence how much VRAM is needed. If your game runs at maximum settings, for example, then you’ll likely require more RAM than if it were run with lower options enabled.
It’s essential to remember that VRAM isn’t the only factor determining VR performance. Other elements like graphics card processing power, memory bandwidth, and cooling systems can also impact performance.
Although 6GB of VRAM is an older selection of cards. As more recent cards tend to opt for more to be able to handle improved graphics and architectural improvements.
