IT ISN'T. Read my earlier posts.

I can max this game perfectly with last 25X drivers. Problem is it would render my other games worthless like Mafia 2, which have had performance improved since.

EDIT: Don't post that systemrequirementslab garbage. All that does is run a system info check. I can max out loads of games it tells me my PC would never even load.

Many thanks for your worthless reply.

Likewise, genius (who can't spell a 5 letter word, it's "throw", not "trow" ROFL).

UPDATE: Just read about the 270 drivers Nvidia just released. Gonna try them now and report back.

+1 to bottleneck
I had a 9800GT on a 3500+ @ 3Ghz and prototype was 3-15 fps
same 9800GT on a Q8300 gave me 50+fps at the same res(1440x900)

There's a reason people keep bringing this bottlenecking point up ... and that's because what you said here, is incorrect ... at least in the general sense (not talking about this game specifically, just in general).

The reason the card downclocks to low-power 3d is because not enough stress is being placed on it (i.e. gpu usage drops below a certain point ... in my experience that is usually around 30%). A severe cpu BN, in the sense that it will essentially impose a framerate limiter, can prevent the GPU from running at it's full potential. Basically, the 'load' being placed on the card becomes 'too easy', so the card downclocks.

Like I mentioned above, this happens with mine all the time since my cards are way overpowered for a lot of games, esp. console ports. So when my usage drops down to like 25%, the card(s) will drop to 405MHz, and then the gpu usage jumps up to around 50%. But it's totally seemless on my rig, no stutters, no FPS drops, no problems at all. The only way I even know about it is because I'm watching the OSD in Afterburner.

Have you noticed there's a pattern to when the card downclocks, i.e. does it only happen when the GPU usage is low (use AB OSD to check this, if you aren't already)? If it's happening with the load prior to the downclock at >50% (I say 'prior' to the downclock because the load will jump up when the card downclocks, for obvious reasons), then there is something wrong with the hardware, because that shouldn't happen.

Bottom-line, while the BN explanation may seem to 'not make sense' to you in regards to this particular game, people's 'logic' (in general) here makes total sense.

I could almost max it on a 8600GTS, and could fully max it on a 8800GT and my old 2900XT with every setting on highest with the EXACT same rig).

=.=
Just to be clear, I'm not going on record saying 'this problem IS being caused by a CPU BN'. However, this particular evidence against that possibility is ... not compelling. Those cards you speak of are all considerably less powerful than your current card. Less powerful cards are less likely to be bottlenecked by a less powerful CPU.

Here's some more proof. I don't know what else I can try to get it to stop downclocking/downvolting. I remember my friend having this same problem with an 8800GT back when it was released, same thing with GTX 280. For God's sake Nvidia, if you can't be bothered to fix your drivers at least let us run our cards at full speeds without this power saving BS.

Settings were all highest with 16xQ CSAA no vsync. Tried Vsync on double/triple buffer, only makes it far worse. Tried 4x/8x MSAA, again fixes nothing.
I understand your frustration, this shouldn't be happening. In nV's defense, I'm pretty sure that there's something about XP that makes it impossible for them to implement the 'switch' to full power mode that you're asking for. I don't think it's 'laziness', IOW. XP can't support a bunch of other stuff, too, like quad-SLI for example.

And I also understand that you're just looking for a way to 'turn it (power-saving) off', you aren't interested in things like the 'underlying problem'. But you are coming off a little rude-sounding toward people who're trying to help you. They are not 'wrong' in suspecting CPU BN being the issue here, because like I said, a CPU BN CAN cause this exact issue.

V-Sync is for sure not the path to a solution, in fact, as you discovered, it will work in the exact opposite direction.

Also ... the 8800GT (nor the 8600GTS) did not have a 'low power 3d' mode. In fact I don't think they even had a 2d mode if memory serves. So you are misremembering what your buddy's 'issue' was. Sorry

My best advice remains what I suggested above: a bios mod to replace the values for the low-power 3d clocks with the values used for full-power 3d clocks so the clocks won't change on low load. You can always flash it back to the original bios when you move the card to your HTPC ... flashing back takes like 1 minute.

That, or update your OS ... because ultimately I think the problem comes down to XP lacking the ability to do what you're asking for.

now that i think about 3D profile
i can set my 2D profile the same as 3D profile, and it forces the 2D profile to run at max everything without powersaving
program is called NvidiaInspector 1.9.5.5 (its in the overclock settings)
one thing, you can't overclock the voltage, so that one stays at the 2D profile (mine is at a minimum of 0.913volt and in 3D i can change it from 0.913 to 1.10volt)

lolwut max??
if a 3500+ bottlenecks a 9800gt and a 460 stomps on a 9800gt sli then what will your single core do to a gtx460?
I`m talking from experience
