Nvidia Borderlands 2 Tweak Guide online

I really like this part about nVidia, the step by step tweaking guide.
Maybe I can get BL2 running like its supposed without the big slowdowns now.

Averaging 60fps with a 660ti @1080p and max settings with max physx seems reasonable to me.

I wasn't commenting so much on the playability, just the impact of PhysX. Most games take a 25% hit at most. It shows that the PhysX effects in BL2 are the most demanding of the various graphics effects on offer - not surprising in a DX9 game.
 
Nice to see Koroush Ghazi writing for nvidia I remember his articles from tweaktown and tweakguides.com they were always a good read.

I agree. On the whole I'm seeing a excellent balance of effects/ physX hit and overall game play fps. As good a execution I can recall. In terms of absolute fps drops because of gameplay physX effects.
 
I ran from the desert teleportal straight across to another map entry point and shot about a dozen skags and a couple birds. I posted this in the long cpu/gpu thread as well but being the topic is physx's impact I thought this was interesting as there is a huge performance impact in my 690. This is mostly just cruising across the desert and I couldn't replicate the dozen kills precisely but you can see the average regardless.

Nvidia are a bunch of liars. Physx high absolutely does not cause a performance hit, ever. In fact, my performance goes up with physx. /joking

Obviously we may have judged a gpu's performance on a given benchmark or gameplay scene from the amount of fps achieved. PhysX will have a larger effect on gameplay fps than average prior quality settings .
PysX's goal is to give high in-game visual fidelity/experiences that have never been seen before. Also to keep FPS high, or high enough for competitiveness, while delivering realistic, exciting graphics.
 
I know, I was just kidding, it wasn't meant as a slight to physx..... Mostly a joke related to how wanderer was given such a hard time, but its whatever.

So there's one annoying thing - shadows seem to have a very aggressive LOD setting? I made a video:

Any way to increase the distance this happens? By a lot? 😛 It's not mentioned in the tweak guide... all settings are maxed already in options.

Unfortunately Keys never got around to formally benchmarking BL2, but your results aren't surprising based on other games. PhysX can only use a single GPU, so it has a bigger impact on SLI setups (including the 690) due to how it messes up AFR timing.

Yes this is true. The GPU doing PhysX has to context switch from rendering to PhysX then back again per each frame. To maintain synchronization the other GPU must wait. While you will likely still have higher frame rates, the performance hit, percentage wise running PhysX is generally higher with SLI.
SLI is where a decent dedicated PhysX GPU can really be of help. My SLI 580's with a dedicated 470 run nearly as well as SLI 680's and my frame rates are more stable. Granted when not running a title with extensive PhysX the 680's pound my 'lowly' 580s'.
