| 4 | PowerVR is a Vulkan driver for Imagination Technologies PowerVR GPUs, starting
|
|---|
| 5 | with those based on the Rogue architecture.
|
|---|
| 6 |
|
|---|
| 7 | The driver is **not yet fully conformant** so it requires exporting
|
|---|
| 8 | ``PVR_I_WANT_A_BROKEN_VULKAN_DRIVER=1`` to the environment before running any
|
|---|
| 9 | Vulkan content.

| 21 | In some cases, a product name is shared across multiple BVNCs so to check for
|
|---|
| 22 | support make sure the BVNC matches the one listed. As the feature set and
|
|---|
| 23 | hardware issues can vary between BVNCs, additional driver changes might be
|
|---|
| 24 | necessary even for devices sharing the same product name.

|
|---|
| 28 | Note: GPUs prior to Series6 do not have the hardware capabilities required to
|
|---|
| 29 | support Vulkan and therefore cannot be supported by this driver.
