Yes, those Windows games are anomalies that rely on the OS scheduling them AS IF they were real-time, but without actually claiming that priority. Because these games just assume they own the whole system and aren't explicitly telling the OS about their real-time requirements, the OS has to guess instead and can get it wrong, especially when hardware capabilities advance in ways that force changes to the task scheduler (multi-core, hyper-threading). And you said it yourself, many old games don't work well on dual-core systems. I think your effort to improve the guessing is a good idea, and thanks. Just don't dismiss the idea that games do have real-time requirements and if they did things correctly, games would explicitly specify those requirements. -- Zan Lynx <[email protected]>
