Hi-Res Textures causing slowdown (remedy?)

(Protip, overclock more if you can. If you can't, some Arctic Silver 5 is $7, and a better cooler altogether is $30 or $75 depending on your needs. A new CPU/motherboard may or may not be out of the question, but it's kind of a waste to replace a 2500K right now...)

Safe texcache accuracy is required for most texture packs, and having any textures work in lower accuracies is mostly just pure luck for you (there's an actual explanation to this, but I don't wanna bullshit it). OpenMP Texture Decoding might help keep things speedy at higher texcache accuracies, though – try that out. In many cases it just slows stuff down, but I think that may be just when trying to decode too many small textures at a lower accuracy, thus the overhead of spawning threads reduces performance. In this case you've got high-res textures at a high accuracy, so each little thread has more work to do, outweighing the cost of spawning it and increasing the amount of work that can be done simultaneously. (Disclaimer: I don't know exactly how this is implemented and how OpenMP does threading, so don't expect this theory to be correct.)

I actually already have some Arctic Silver 5 and a Coolermaster Hyper 212 Evo installed . It has been about 1.5 yrs since I applied it though. I might need to re-apply some AS and the HSF to get better heat reduction. I was able to OC to 4.7 and boot and run some stuff, and even play Mario Galaxy, but I was less stable. Perhaps I'll mess w/ the voltages a little more, and run a burntest to actually get a stable system at those higher clock speeds.
I will dig more into the settings tonight with the OpenMP Texture Decoding, and try out a couple of different texture packs on less demanding games. Will report back the results.
