Bullet Train was seeing ~15 – 20% CPU improvement on the render thread and ~7 – 10% improvement on the GPU. 5 - Freezes/Pauses game after a delay. 1000 ms in 1 sek = 1000/30 = 33,3 ms to render frame. There are two main ways of doing this. 4. Also this MSDN thread seems to have good advice. Particle simulation times (Tick) are calculated on the Game Thread. This allows to render a multitude of objects before switching the parameters with another draw call. Sorry! Cause of the usage of object instances the draw call/poly count is really incidental, but it makes the simulation looks more realistic. That’s the power of batching. GPU Profiling#. Unlike in the paper, we don't perform the optimization of joining all light sources coming from the same axis into one propagation pass. Rendering Flow.

Writing to video memory has to go through PCI bus, which has a limited bandwidth. Table of Contents: Rendering code. Limited register space, memory latency and SIMD occupancy each affect shader performance in different ways. And UEs multithreading is limited (you have mainly two threads, the game thread and the draw thread, so if you have a multicore CPU the CPU usage shown in the task manager will always be low) and I don't know what the GPU usage in the task manager means, even if I'm GPU bound in my project it only shows a couple percent GPU usage, whereas nvidia-smi shows 98% usage which is more likely =) Feb 21, 2017 · Part 3 of 3 - This is a tutorial to help developers improve the performance of their games in Unreal Engine* 4 (UE4).
