New tweak might help some

I've just read an article saying that for some applications, turning off "Snoop filtering" in the BIOS can lead to improvements.Turning it off in my PC (a Dell Precision 690 with 2x 5160 Xeons in a 5000X chipset) leads to a slight but discernible improvement in framerates with FSX. I haven't been terribly scientific about it but given the same situation and settings, the "before" FPS bounced between about 25 and 30; the "after" FPS bounces between about 28 and 33.Sorry if this is old news: I hadn't seen it elsewhere before.Tim

I haven't heard of this.I wonder if it is something that I'm already turning off in AclarityPC.

Alacrity PC turns off applications and background services. It does not affect BIOS settings.Apparently the "Snoop filter" is something done at hardware level. It's meant to improve use of the CPU's cache RAM - but in some situations it seems the better memory management is not worth the extra clock cycles (or whatever it is).Tim
