# Headless Chromium with GPU acceleration
|
|
#
|
|
# For pre-warmed browser pools via fork (warm-state preservation, the required
|
|
# --no-zygote/--no-sandbox flags, persistent-workload setup, and CDP access),
|
|
# see README.md in this directory.
|
|
#
|
|
# Guest Vulkan (Venus/virtio-gpu) forwards calls over the virtio-gpu transport
|
|
# to the host GPU. ANGLE inside Chromium uses Venus as its Vulkan backend, so
|
|
# WebGL and compositing run on real hardware — no SwiftShader fallback.
|
|
#
|
|
# Confirmed GL renderer:
|
|
# ANGLE (Intel, Vulkan 1.4.307 (Virtio-GPU Venus (Intel(R) UHD Graphics 620
|
|
# (KBL GT2)) (0x00005917)), venus)
