Why CPU Speed is more important than CPU Core Count

[Ed P]

Basically because writing multi-threaded/multi-core game engines that optimise CPU core usage is really hard. Even if you are not a C programmer, you will get a lot out of the following link as it takes you through all the problems on writing threaded game engines and gives a little insight on how they are designed with especial reference to the Unreal engine. It also gives a little insight into why Linux games pre-Vulkan ran like a two legged dog.

An interesting read as non-programmers can just skip over the code examples.

Windows knows best?

I see the new defense strategy is out. It makes my skin crawl at the capabilities of our military dealing with a cyber attach. I bet they duno what Caps lock is or a bad gateway.

Unfortunately the same game threading issues apply to Windows too!

Its amazing that almost no one mentions that mutex is short for mutually exclusive, just knowing that explains a lot about what they are.

The Windows internals books do actually tell you what mutex stands for, ONCE, but it is buried deep in a chapter that starts out being about something else so its easy to skip over (I did, at least 3 times).

I cannot make a new topic (Forum bug?)!

However if you get Gremlins in your wfi or SSDs it could be that they are interfering with each other. Unleash the tinfoil hats!

I have to wonder about PC cases with a window in the side too, if that doesn’t let RFI escape I don’t know what does.

Just for completeness this YouTube gives some tips on RFI shielding for components.

The very last tip is worth watching for its innovative sandwiching of heat shrink tubing and tinfoil.
