VirGL vs Turnip performance

[pemgithub]

1: Which is faster - VirGL or Turnip?

2: Suppose VirGL was pointing to an Android build of Turnip (with a rooted device). Which would be faster - VirGL pointing to Android turnip, or Turnip in mobox (termux)?

3: Or suppose the proprietary Vulkan driver for Adreno is built for Linux. Which would be faster - VirGL pointing to the proprietary driver built for Android, or the proprietary driver built for Linux running in mobox (termux)?

4: Can someone give a technical explanation of which is faster and why - especially for 2 & 3. I realize for (1), it's weird because we're talking (VirGL pointing to the Android build of the proprietary driver) vs (Turnip running in mobox termux)
