Fix: Performance sucking on Dual Core and HT CPUs
dizzy:
All of this makes sense of course *if* the CPU is the speed bottleneck, which is not likely to be the case with a relatively modest but modern system. A smokin' hot bleeding edge in every conceivable way system may benefit from this.

TS2 is a CPU hog, so yes, CPU does tend to be the speed bottleneck. The graphics themselves are actually mildly outdated and don't tend to bottleneck a modern system.

By that I simply meant that the CPU tends to be less the performance issue than your average hard drive or RAM speed. Most people still tend to have slow drives and slow RAM, even with relatively modern CPUs.

Yes Ste you could dump SD2Hider and the ForceCore thing with HT turned off, check and make sure none of her programs need HT for anything before you do that though. How you'd go about doing that, I have no idea but the only things I've come across that actually use it are Adobe Photoshop and a glide3x wrapper but that's just me.
Dizzy, hard drives aren't really a factor unless your pc doesn't have enough ram (thrashing the hard drive with the Windows swap file usage). About the only difference you'll see with slower hard drives is the initial load time, and even then Windows has the ability to prefech and keep that data in ram if the game is loaded often enough. This laptop has a 4,200 rpms hard drive, but since it has 2 gigs of DDR3 ram you really don't notice it (especially if you set the executive kernel to only stay in active memory). It's the same with my 3 year old desktop (1 gig of DDR2 ram, it was 512 megs before). I don't remember the clock speeds on the ram right now, but I didn't break the budget on them they're the averagely priced modules.
Best case scenario, the hard drive is used very little only loading data when a neighbor walks on the lot (~300KB and ~5megs for clothing, hair etc. most of which will be held in video memory for the different texture LOD stages) as everything else should already be loaded in memory. Let's face it, any normal lot does not include all 7 gigs of data that makes up this game so it'd be safe to assume that all the data needed for that lot can easily fit into 1 gig of ram maybe even 512 megs for a small lot. Hard drive speed really has no influence in anything besides saving and load times or if your pc has so little ram that it resorts to using the slow swap file.

I tried both doing this and turning off HT on my system, and I get noticeably better performance in TS2 with HT turned off. Let the 3Ghz processor have at it with no distractions. :)
