FPS Doesn't Change

No matter where I put my video settings, no matter which
level, I only get 15-20 FPS (which looks laggy) with most vehicles,
even on Grid, Pure. (blank level)

I switch to the DSC Buggy and I get 80 FPS.

When I first launch the game I'm getting 220 FPS on the start screen.
The Gavril D drops onto the Grid, Pure and blah....18 FPS.

Why are the basic vehicles in this game so FPS intensive?

I have a dual core cpu with 4GB of DDR2 RAM and an
HD 4850 GPU.

CPU runs around 80% at 42°c
RAM stays around 50% usage
GPU temp increases 4° from idle, as if I never opened the game.?

I don't expect to run anything on high with this setup but I'd like
to know the reason I can't to get at least playable frame rates on
the lowest settings...?

There's another "car driving/crashing" game coming out that has
a tech demo also and I get 40+ FPS with that game at highest
settings with the same rig. ??

 

If you pause the game, what is your FPS?

 

When I press "J" to pause physics I get 220 FPS.

If that's what you mean by pause?

 

It's your dual core CPU, you're very CPU bound. BeamNG is a really CPU intensive game and there is no game you can fairly compare it's usage to as it's the most realistic.

Can you get decent FPS with the Ibishu Covet?

 

I'd consider that a known issue I guess...
are there any plans on shifting some or most of the processing
to the GPU in the future? That would seem to make more sense, no?

Nowhere near decent. I get 21 FPS with the Ibishu Covet.

 

dual core with an HD 4850. You are in minimum requirements http://wiki.beamng.com/Requirements

 

It's not a "known issue", it just is, BeamNG is calculating a 1000+ nodes and beams 2000 times a second. No other game does anything like this. The game has state-of-the-art ("smooth") soft body physics which are ahead of its time (which is a good thing) and needs a lot of CPU power. And no offense, but your specs are really outdated.

Using the GPU to help calculate the physics I think is a possibility in the future. The race update (the next update for BeamNG) will have a ~20% performance improvement for the physics so that should help you.

 

I am aware of this, thank you.

I just wondered why I can get 80 FPS with one vehicle and
only 18 with most others.

I would expect to see a performance decrease switching to a more
complex level with more terrain and textures, but just changing
vehicles makes it unplayable.

 

Some vehicles are a lot easier then others on the CPU's physics calculations. Terrains and textures are always rendered by the GPU. Remember you are CPU bound so you have wiggle room for the GPU's work and not for the CPU's work.

 

So to answer my original post, it's because the game is almost entirely
dependent on CPU power to execute most of the games critical functionality,
which is probably why it's still in Alpha.

I'd think you'd want the work to be shared with the other hardware also.?

I just found it curious:
CPU @ 80% and 42°c (not exactly maxed out)
RAM @ 50% usage
GPU @ basically not being used

I think the Requirements wiki page will get some serious overhauling
before this game reaches RTM.

 

It being CPU bound is not why it is in alpha at all. Software does not move to beta until the software is feature complete, BeamNG is not feature complete at all.

Go read the BeamNG homepage, OpenCL is already mentioned on there as a future possibility, but its very hard to integrate such technologies and could introduce alot of bugs. I wouldnt expect that to appear until much later in development.

The next update offers a 20% speed increase on physics calculation which should help you significantly.

As for drowsy sams buggy working so well, it has less nodes and beams in comparison to the stock vehicles (which have about 4-5000)

 

I have the same problem, BeamNG is a REALLY CPU heavy and, chances are your GPU is being bottle-necked by your CPU.
I have an R9 280X (Reskined 7970) and an AMD fx 6100 I also get around 20 FPS. I'm going to get an AMD Fx 8350. So I'd recommend upgrading your CPU when you can.

 

That's exactly what I meant, I just didn't elaborate.
"I'd think you'd want the work to be shared with the other hardware also.?"

Good lord....if that was the case, I would pass on this game altogether.


My personal pc (in my signature) has no issues with this game.

The pc with the issue is my 11 year old sons pc.

 

that doesn't make sense... the computer in my sig gets 20fps at base clocks.

 

trust me, beamNG will flex the GPU , you're not seeing any usage on a grid map maybe but in deep forest maps the gpu is working hard, i have an old but still decent card and it flexes with the heavier maps, i can't imagine running the game with any less hardware than what i got now.

the "work" is shared, when you have a heavy map and a few cars , a balanced (high end sure) computer will be working with cpu and gpu to bring the FPS

but you're talking about CPU load, its an Alpha, not even considered beta, what were you expecting? :S have you played rigs of rods? basically the same game ?

his pc is not a balanced setup, his gpu far out performs his cpu, thats expected to happen. so "if that was the case" for me I would go change the cpu and balance the setup out because thats a ridiculous combination

 

For the off-loading to gpu thing, the devs have said they plan to eventually have Open-cl support

 

I have the same PC as you, except I overclocked and I have a 270X HAWK. I get at least 35 FPS on most maps, even when not overclocked (except for the Cabster and Caddy).

 

Ive been seeing countless threads about people changing graphic settings with no FPS change, as many of the people have responded, its CPU.

The reality of things is that your CPU is MUCH more powerful then your GPU, so games like BeamNG and Planetside 2 load mostly on CPU leaving the GPU to what it was designed for (although GPU does handle physics most of the time). As for doing a hybrid of sharing load between CPU and GPU, Im not sure if that would be possible, my guess is that it would be rather inefficient

 

as said many times, the devs have said that they plan to support opencl, which allows you to off-load some of the physics to the gpu (and it wouldn't be inefficient, provided opencl support is added correctly, and considering what we have now, as an early-alpha, im certain that the devs would easily be able to install it correctly)

 

Wrong ... the CPU is way more versatile than a GPU ... as the name suggest Central Processing Unit versus Graphics Processing Unit ...

So a CPU can handle alot of different stuff that a GPU can't do. But GPUs can do Graphics and stuff that can be highly parallelized (hint: graphics are highly parallelized).

Performance-wise a modern CPU gets around 0.2-0.3 TFlops whereas a GPU can achive 5-6 TFlops (that's about 20 times more performance - but in specific scenarios!)


As for the topic: Don't expect your 5-10 year old dual core to do wonders in a modern game/physic-sandbox.
