So, that 4 year old information is quite dated at this point.  I like making new posts about performance comparisons.

This is a controlled(able) test method of my own design to get a benchmark result, your mileage will vary.  I move my camera into the sky on a sim in SL that has no people present other than myself. Record the FPS. Post it here. This is not typical of a dynamic location in Second Life as you move around, with that many variables in a dynamic it would be impossible to create a real benchmark.  It’s a controlled benchmark test. All systems are not overclocked at the CPU or GPU level beyond the factory settings OC on GPUs out of the box.

Graphics Settings in Firestorm Viewer are set to Anisotropic ON, SMAA, and HIGH, the limit frame rate feature is disabled.

Observation: The January 2026 and newer versions of Adrenaline for Windows seem to have significant OpenGL optimizations made by AMD, this does not appear to apply to the rocM for linux drivers created by AMD.
