Did a bit of testing with some of my players at the weekend, some observations; 1. My machine Win 11, Intel I7, 16Gb and 620 onboard graphics card & Firefox, map 50x30 with dynamic lighting; Original Roll20 CPU ~50%, GPU ~75% Jumpgate CPU ~30% GPU 99% Subjectively felt a bit slicker moving around 2. Player 1 Linux Mint lenovo laptop, 16Gb, not sure of processor/gpu probably onboard & Firefox, map 50x30 with dynamic lighting; Original Roll20 CPU ~85 GPU ~80% Jumpgate CPU 100%, GPU unknown, could not display the map at all (black screen) and the m/c crashed after 3-5mins of trying. Unusable 3. Player 2 Win 10, Intel I7, 8Gb and 610? onboard graphics card & Firefox, map 50x30 with dynamic lighting; Original Roll20 CPU ~70%, GPU ~80% Jumpgate CPU ~30% GPU 99% Subjectively felt a bit slicker moving around, said the had a couple of 'stutters' moving around the map - probably the GPU maxing out. None of my players use Chrome due to it being a memory/processor hog. Gonna try and repeat these tests without dynamic lighting as that's almost certainly the cause. Reduction of CPU usage is welcome, although it appears to have been achieved by offloading much more onto the GPU, this is going to cause issues for anyone using onboard graphics.
