Nalu Demo jerky framerates

I had the problem where it didn't play at all. Try ninstalling the forceware
drivers, (use something like driver cleaner 3.0 to make sure the job is done
fully) re-install them (I used the forceware 66.00 drivers, but note they
are not supported), and also make sure your Mobo drivers are up to date,
that sorted the issue for me.

I bet it's because you have 512mb of ram. High frame rates in timedemos but
jerky motion in real-time action means you need more ram.
I just went through this with Doom3 and Far Cry. With 512mb my 3dMark03
score is 12,901. My Doom3 timedemos in High quality were OK, but game action
was jerky even at 800x600, so I played at Medium quality. I borrowed 512mb
from my kids' computer, mismatched timing and all, and I can play Doom3 at
High quality, card settings all on quality, 2xQ AA and 8xFA at 1600x1200
smooth as silk all the time.

Thank you for your suggestion. As it is, I plan to upgrade the ram next.

No no, no no no!

What actually happens is the opposite

Ram/memory has NO (or virtually nill) bearing on realtime FPS!!!
It is in fact the other way round when benchmarking. Timedemos will be
considerably SLOWER on a system with less ram as halfway through the
timedemo the HD will swap and stall the timedemo for a second or 2.
This in turn will ruin the average fps of the demo as to all intents
and purposes for a brief period your getting 1 fps for a good couple
of seconds (instead of your 30-60fps whatever). Now this can happen
repeatedly during a timedemo everytime reducing the final score. But
on the whole your REAL fps will remain unchanged.

On a machine with an inadequate amount of RAM run the time demo a
*second* time and watch the final score shoot up to see what I mean.

This also means, in the game if you just get current onscreen fps (or
timerefresh) the amount of RAM should have no bearing AT ALL, unless
of course the HD is swapping at the precise second you do a
timerefresh.

Essentially this means. When you have a low amount of RAM your fps
will be the same as if you have 10gigs of ram. Except every now and
then your screen will freeze while the HD swaps the info in/out of
RAM. But outside of memory swapping your fps scores will remain
unchanged...

"No no, no no no!" ?? Why is it that people get most emphatic when they're
wrong?
We're talking about jerky gameplay and large textures like those used in
High quality mode in Doom3. In the 2nd timedemo, textures are cached, so the
frame rate goes up. In game play, if the textures aren't cached in RAM, the
motion won't be smooth.
I think, for the most part, your examples are good, but you're drawing the
wrong conclusions. If you have 512mb of RAM and are playing Doom3 (or Far
Cry) and getting jerky gameplay, going to 1024mb should clear it up. It
worked for me, and it's easy enough to test for anyone else. In High quality
with 512mb of RAM, my cached timedemo frame rates were fine, but in the game
I was getting slowdowns when something unexpected happened; like new
textures, opening doors, muzzle flash or firing monsters jumping out at me.
Then the game stuttered. Going to 1024mb cured it. 512mb is fine for Medium
quality, but you need 1024 for smooth gameplay in High quality.
Adding more RAM for smoother gameplay isn't anything new.

Yah but...

Specifically the tech demo. Nothing new comes on screen. There are NO
suprises, its the same scene no matter what you fiddle with. No sudden
need to load textures in etc etc. Even if that was the case. Slowdowns
of that order are short lived (and result in some obvious HD churning
and don't result in *general* shite fps.

I do see what you mean that if the scene physically has too much
onscreen (texture wise) it's going to stutter <see below>, as textures
will constantly have to be swapped about. But on a system like his
system RAM won't be the issue. I believe it's the fact his CARD only
has 128megs where as the majority of people that run that demo have
256meg cards.

I remember a case like this when playing Quake3 on my old 32mb
GeForce. THIS is an example of the card running out of texture memory.
I was playing a user made map (lots of purdy textures) at 1280 it was
fine, wacking the resolution up to 1600 caused stuttering but *NOT*
due to the card falling to it's knees but due to the card running out
of memory, and you can tell the difference...*
Oh and this was not helped by increasing system memory, as access
between system RAM and the card is not fast enough, compared to the
card accessing it's own RAM


*When you run out of texture mem or there are other issues, the
stuttering seems a little more random. Say 0.25 secs of slightly
smoother display then some odd stuttering and so on. As opposed to if
your card just doesn't have the grunt to shift the polygons around
where you will basically just a generally slow and jerky game (not so
much random stuttering)

There were a few other things that suggested this assumption also but
I cba to explain them:-)

It's hard to explain but you will know the difference if you see it.<!-- ~MESSAGE_AFTER~ -->

LOL. OK, we'll see
Hopefully Vaughn will get back to us when he upgrades his ram and let us
know.
In the meantime...... last night after I shut down, I took the 512mb I
borrowed from my kids and put it back in their computer. My extra ram is
scheduled to arrive today before 4:30. Oh... I got a great deal on 2x256 OCz
3700EB from newegg's refurbished page. I asked Tony at OCz if I should try
refurbished memory and he said "Sure, it's got a lifetime warranty,
remember?". DOH. The EB let's me go to 2.5-2-2-6 timing and these 875/865
motherboards love the tight middle timings.
Anyway, I hadn't tried the Nalu Demo before I saw Vaughn's post a couple
days ago. It ran great with the 1 gig of ram I was using. Before I install
my new ram, I'll try the demo again with only 512mb of ram. Maybe I'll even
run home for lunch and try it.
I'll let you know what happens. Maybe someone else here can try it, too.

Went I went to 1024MB from 512MB everything smoothed out during gameplay
with my 6800 GT.

I did end up trying this. Nalu demo ran OK. The biggest difference was
slight pauses when I clicked menu items.

Hi there Im sorry to bring this topic back to life but I to am finding
the Nalu demo jerky also . Here are the Specs to my PC for you good
people to evaluate.

Motherboard: Gigabyte GA 700N Pro ( IDE Raid Board )
Athlon 2.6 XP 333 FSB
2 ATA 133 60 gig 2mb cache 11ms 7200rpm Hard Drives
Memory: 1 Gig 333 Mhz PC2700 ddr ram
Graphics Card: Evesham GeForce 6800 128MB DDR AGP (OEM) ( Nvidea 70.90
drivers not digitally signed Im using Although I have used the latest
ones which are signed and it was still jerky. No Overclocking of the
card. Running as Standard.)
Power Supply: 550 watt recently bought from Novatech to power my New
Graphics Card.
When I go to DXDIAG it tells me I have 1024 MB of ram.
I downloaded the latest Bios to my PC which is F17, but I changed
nothing in the bios beacuse I thought to leave it as it was. Obiously
something is not right because it is so jerky. Any help greatly
recieved as I am a total novice here. Thank you on advance.

Very easy to fix this, the 128 MB cards do not run Nalu smoothly with your
BIOS AGP aperture set to 128MB or below, Go in to your BIOS and change to
256MB and it runs perfect. The 256MB version of the 6800 does not have this
problem.<!-- ~MESSAGE_AFTER~ -->

I am experiencing a really bad frame rate as well. I have a gigabyte
nforce4 mb with a gig ram, 6600gt pcie video card and I get like 1
frame per sec. I have 66.xx (dont remember the exact iteration) video
drivers. It was working for a short period of time when I first
reloaded XP but since then the performance is horrendous. Anybody have
a clue?
