BF3 was beautiful

Once again thank you!
It's so nice to have all the good tweaks bundled together like this

You are welcome guys!

Now I'd like to remember people about the value of HPET enabled in BIOS and high timer resolution:

As you see HPET don't affect CPU performance but you gain an average 10% performance (10%+ FPS) for GPU, you gain also a bit of disks performance (units: lower is better).
I disable PerfectDisk services/drivers for that reason too, slight performance gain. I enable them only when I choose to optimize my SSDs.
For HDDs, UltimateDefrag is best because you can prioritize placement of your favorite games folders on the outer (fastest) rings.

By the way, I highly recommend to buy a OCZ Vertex 4 if you look for a SSD, I think the Indilinx Everest 2 controller will stay the top dog for quite a few months with the new high performance firmware.
Here some kind of "personal evolution" on the disks front:


For BF3 specifically, in your user.cfg, create one if you don't have one already (C:\Program Files (x86)\Origin Games\Battlefield 3 or where ever you installed it), write this in it if you don't use V-Sync:

RenderDevice.TripleBufferingEnable 0
RenderDevice.ForceRenderAheadLimit -1 (which refer to default drivers value, AMD & NVIDIA)

I still have to test if ForceRenderAheadLimit change something on AMD card, but default or higher should be best, not lower.
On NVIDIA, I enforce 999 for every games in my custom global profile. Sure it don't even go up 4-5 probably, it's only an arbitrary maximum but I have good result with it.
2 look the very minimum for smoothness.
Whatever, there is no gain with this setting below drivers default value but you gain in smoothness on higher values without lagging penalty from my experience. FPS hit is insignificant too, I'll test that scientifically someday.

I hope it's useful to some, have a nice day guys.
