Description

Perf on FASTDBG (20220411 and tested as well on older builds such as 20210603) is slower than expected, including on retail assets. 36fps on surrender belisarius vs 120fps on release builds.

Drops to 24fps with frame data profiling with a major frame time loss on Render HUD Gauge - unclear if the HUD is the main cause or simply skewing the profiling because of the data being printed on screen.

My hardware: i3-8100, RX480, 16GB RAM, windows and game data on SSD.

Similar perf loss with and without frame data profiling reported by EatThePath on an old laptop of his.
