NVGs and frame rate

[fox_111]

I usually get good frame rate in BS when there is not too many ground movement and metal travelling in the air.

 

But when I switch the NVGs on, my frame rate drop to something like 2 to 5 fps.

 

Computer spec

 

Intel pentium 4 Core2 2.33GHz

2Go ram at 2.34 GHz

GeForce 8600

onboard sound card (I know, next purchase...)

 

I run BS on almost max setting except for textures set to just bellow max resolution.

 

I also set the shadow to the medium level (just before the max, so the rotor does not cas shadow...)

 

Anyway to fix the unplayale fps with the NVGs?

That looks strange. I've tried that on my laptop which unless I've misunderstood components is worse. Specs on that rig:

 

Intel Core2Duo @ 2GHz (I assume that by "Pentium 4 Core2" you mean a Core2Duo.)

2 Gigs of CL5 RAM running at 333MHz (Do doublecheck your RAM speed btw, a 2.34GHz RAMstick is something I'd pay a lot for.)

GeForce 8600m with 256MB dedicated VRAM.

Onboard sound.

Vista 32 Home Premium.

 

Which operating system are you running there, and is that a laptop? In my experience the drivers for laptop versions of GPU's are very hit-and-miss and can cause all kinds of funniness.

 

I'm not at all sure what method BS uses to get the NVG effect - if it's some kind of post-processing of the image it might cause some added stress on the GPU, but in that case the same thing really should have happened on that laptop of mine as well since I usually had it quite playable even with full shadows and blur.

BTW, for a nice look into your computer components, check out this application: http://www.cpuid.com/cpuz.php

 

It will help with lots of things, such as observing occurances where a component that should run at speed X instead is running at speed Z, which might indicate that some BIOS tweaking or driver updates (or downgrades) might be in order.

It's a PC

 

Windows XP up to date.

 

Ram frequency, I'm not sure now, the GHz was written on the same line.

I just know it's not crappy RAM. I should fetch the spec list from when I bought the computer, it's a custom built one.

Get CPU-Z, it'll tell you everything you need to know and give you a chance to spot things like dynamic undervolting happening to cause your computer to get lesser performance.

 

However, I really don't see how that stuff would cause a problem specifically with NVG's. Do you have nHancer forcing Anti-alias or something like that? A few of the settings in nHancer have caused some funny behaviour in black shark on my main rig.

[fox_111]

Good idea about nHancer, I'll check it and run some tests.

Update.

 

I checked my graphic card settings, and I turned ON the multi core support in the GeForce setting only for blackshark (Not in global setting).

 

It did the trick. I went from less than 5fps with NVGs on to a steady 20fps wich is plenty enough to be smooth.

Awesome. :)
