Description
Returns the average value of the required texture pool "r.streaming.PoolSize" since engine start or since the last ResetAverageRequiredTexturePoolSize(). This value gives the perfect value for "r.streaming.PoolSize" so that the streamer would always have enough memory to stream in everything. The requirements are different depending on whether GPoolSizeVRAMPercentage > 0 or not. When GPoolSizeVRAMPercentage > 0, the non streaming mips are not accounted in the required pool size since StreamingPool = Min(TexturePool, GPoolSizeVRAMPercentage * VRAM - RenderTargets - NonStreamingTexture) This means that the StreamingPool = TexturePool, unless there is not enough VRAM Otherwise, when GPoolSizeVRAMPercentage == 0, StreamingPool = TexturePool - NonStreamingTexture. In which case "r.streaming.PoolSize" must account for the size of NonStreamingTexture
