Virtual reality (VR) gaming requires sufficient VRAM, as this determines how much data can be stored and accessed by your graphics card when rendering high-resolution images for both eyes.

With more VRAM, more textures, models, and other game assets can be stored in memory, which leads to smoother VR experiences overall.

So, is 8 GB of VRAM enough for VR gaming?

The answer depends on the game and graphics settings that you plan to use. In general, 8 GB is sufficient for most current VR titles when using a headset with 1440×1600 per eye resolution or lower.

However, if using high-resolution headsets like the HP Reverb G2 or the Valve Index, more VRAM may be necessary in order to achieve the highest graphics settings without frame drops.

It’s essential to note that VR gaming puts more strain on a PC’s hardware than traditional gaming since two high-resolution images must be rendered simultaneously.

Therefore, the overall system configuration is just as crucial as VRAM; CPU, RAM, and storage speed all play an integral role in performance; having a powerful graphics card with enough VRAM is only part of the equation.

Additionally, some VR games may need more VRAM than others due to their graphics requirements. For instance, those with more complex environments, detailed textures, and high-quality lighting effects require more VRAM than simpler VR titles.

Half-Life: Alyx suggests a GPU with 6GB at a minimum. So one with 8GB will no doubt have any issue running it. With plenty of other titles also opting for that level.

Overall, 8 GB of VRAM is sufficient for most VR gaming scenarios. However, if you’re using a high-resolution headset or want to achieve the highest graphics settings possible, then a graphics card with more VRAM may be necessary.
