The Case of the Locked File

We were seeing frequent file IO errors in relation to temporary files created during cooking (particularly when compiling shaders). Our findings for why this were happening were surprising. Here we present a clean way to fix the issues … Read More

Speeding Up The Time Limit Controls

When a process takes a long time to complete, it makes absolute sense to put some time limit checks in so that you're not starving other work. What you don't want to do, of course, is to have those checks slow your original task down further by any considerable amount - here, we found that exactly this was happening .. so we present a solution … Read More

Portrait Of A Serialize Perf Killer

With performance critical editor and cooker code, it's well advised to consider performance when adding tests for rare errors. Here we take a look at this and show by, by considering the CPU pipeline and code cache, a simple change can yield a significant performance improvement without reducing stability … Read More

Sweeping Up And Disassembling A Physics Macro

Macros can often be useful to make certain programming tasks simpler - but they can also cause hidden performance headaches that might otherwise be avoided. Here we look at one of those - and how to improve it … Read More
