* Implement sync interval and refresh rate API for RenderViewportWidget Signed-off-by: nvsickle <nvsickle@amazon.com> * Measure actual frame timings in the viewport info overlay. Takes the median of the sum of (frame end - frame begin) to provide more a more representative view of when frames begin and end. Note: Until VSync is internally supported by the event loop, this will produce nearly identical frame timings as the frame will spend as much time as needed synchronously waiting on a vblank. Signed-off-by: nvsickle <nvsickle@amazon.com> * Make frame timing per-pipeline, wire up refresh rate info to ViewportContext Signed-off-by: nvsickle <nvsickle@amazon.com> * POC: Frame limit pipeline rendering Signed-off-by: nvsickle <nvsickle@amazon.com> * Switch Editor tick to every 0ms to allow better tick accumulation behavior Signed-off-by: nvsickle <nvsickle@amazon.com> * Move RPISystemComponent to the tick bus, remove tick accumulation logic Signed-off-by: nvsickle <nvsickle@amazon.com> * Add `AddToRenderTickAtInterval` to RenderPipeline API This allows a pipeline to update at a set cadence, instead of rendering every frame or being directly told when to tick. Signed-off-by: nvsickle <nvsickle@amazon.com> * Make ViewportContext enforce a target framerate -Adds GetFpsLimit/SetFpsLimit for actively limiting FPS -Calculates a render tick interval based on vsync and the vps limit and updates the current pipeline Signed-off-by: nvsickle <nvsickle@amazon.com> * Add r_fps_limit and ed_inactive_viewport_fps_limit cvars Signed-off-by: nvsickle <nvsickle@amazon.com> * Quick null check from a crash I bumped into Signed-off-by: nvsickle <nvsickle@amazon.com> * Fix off-by-one on FPS calculation (shouldn't include the not-yet-rendered frame) Signed-off-by: nvsickle <nvsickle@amazon.com> * Clarify frame time begin initialization Signed-off-by: nvsickle <nvsickle@amazon.com> * Fix TrackView export. Signed-off-by: nvsickle <nvsickle@amazon.com> * Address some reviewer feedback, revert RPISystem API change, fix CPU profiler. Signed-off-by: nvsickle <nvsickle@amazon.com> * Add g_simulation_tick_rate Signed-off-by: nvsickle <nvsickle@amazon.com> * Address review feedback, make frame limit updates event driven Signed-off-by: nvsickle <nvsickle@amazon.com> * Remove timestamp update from ComponentApplication::Tick Signed-off-by: nvsickle <nvsickle@amazon.com>
