I'm working on multithreading the SF engine (currently single threaded) to take advantage of multiple cores and allow for scripting in python that won't hold up graphics rendering. Currently, everything we do in the game takes away from everything else.

I'm curious how many cores you guys are running so I know how much I can parallelize the code. If I turn it into 4 threads and you only have 2 cores, not much would have been accomplished.

To find out how many logical cores you are running, hit CTRL-Shift-ESC from your windows desktop and then click on the performance tab. Count the number of boxes in the "Cpu Usage History" area. That's the number of logical cores you have.

For most of us, half of those cores are fake (hyperthreading) cores, but it's good to get an idea as to what people are running regardless.

Also, if you can get your CPU make/model as well, that would be epic. If you click on your windows button in Vista/Windows 7 and type "Device Manager". Then browse to "Processors", copy and paste that text into here. For instance, mine says "Intel(R) Core(TM) i7 CPU    860 @ 2.8 GHZ" x 8. The number of times this is repeated is also the number of cores you have.

Quad core support would be really nice, but can you give some 64-bit support too if you know how to code in 64-bit? (just an idea, not now thou)

I actually just did a 6-month port of my corporate product to 64-bit, and unless you need more than 2GB of ram per process, it doesn't really buy you anything. It's about 20% slower on most workloads due to pointers being 2x as large. For the app I work on, it is a godsend because we don't worry about memory anymore, and the boxes can be upgraded to 12, 24, or 48 GB of RAM. For SF, it will probably always be 32 bit Smiley. Plus, I'm not sure if our network library even supports 64-bit.

4 core support sounds about right. I've got 4 physical cores and 4 hyperthreaded ones.

AMD Phenom(tm) II X6 1090T Processor 3.2GHz
6 cores total

8GB ram if you want to know that as well.

Wouldn't really bother going 64bit anyways, the game just needs optimization and probably this will help a good bunch too if you split up everything, I think max supported should be 4 anyways Smiley

Intel Core 2 Duo CPU T5750 @ 2.00

I need upgrades Wink

I'm not surprised after hearing how expensive everything is in Sweden. 4 cores is plenty.

dual core @2.2 Ghz, with 4 GB DDR2 ram.

but my computer is a bit old, though, and i plan to upgrade to something that's at least quad core, maybe more. (gaming powerhouse, with a kickass everything)

Seems to suggest most people have 2 cores, with 4 starting to become more common. Go for 4  Smiley

Duo Core.

Just want to add that in the future most people will have more cores, currently Duo Cores is most used in the world, Hex-Cores and Quad-Cores are gaining higher and higher percent every month. Think of the future and do 6 Core support Tongue

This is no problem. The problem lies in going from 1 core to multiple. Once you can do that, many is much easier. I'm currently working on supporting up to 16 in my project at work Smiley
