BeamNG is not using my GPU while in a level.

I am using presisionX to watch my GPU load and something is wrong, very wrong...

While I am in the main menu my GPU is being using %99 and I am getting 250+ fps
although when I enter a level my GPU load is anywhere inbetween %0 and %50 and I get about 15 or less fps.

Video Card: ATI Mobility Radeon HD 4830

-----------------------------------------------------------------------------------------------------
Computer that I am building in a month: 4930k, 2way gtx 770 4gb sli

 

CPU bottleneck I'm thinking. What are your PC specs.

 

CPU is only being used %25 or less

CPU = i7 720qm
GPU = ati mobility radon hd 4830 overclocked to 660mhz
HDD = 500gb 7200rpm
RAM = 6gb

 

Most definately the graphics card.

You need a more powerful GPU, and a SSD could help with stability of the FPS. SSD's doesn't do very much for FPS in games, but they do very, very much in eveything else. Makes your computer feel very quick.

But, bottomline: GPU.

 

Thanks. Just picked up 2 GTX 770 4gb for SLI

 

Well, for numerous reasons SLI wouldn't be the best idea.

Not all games support it, the performance gain is highly variable, you may get lower minimum FPS and then there are the famous "micro stuttering" problem.

And, I am not sure if or to what extent it in that case would support it. Maybe, if the support is bad or non existing you could get higher FPS with a single card.

The reason SLI can be good is when you are buying two very cheap cards with a lot bang for the buck. Because mid-end card have more bang for the buck than high-end cards. But again, SLI does not mean 200 % performance by any means. The other reason is when you need more power than the best high-end card can provide and therefor combining several of those high-end cards.


Did you order the cards already? At least the 4 GB versions will give you some good capabilities with high resolutions and high Anti-Aliasing. And it will run BF4 pretty smoothly.

What CPU (and other specs) do your desktop have?

 

I'm pretty sure he can just manually disable SLI for programs that puke because of it in nVidia control panel. Not really something I'd throw extra cash at, but I don't have a ton of disposable income either, so...

 

Then, why "buy SLI" when you would have to use 50 % of the product and turn it off in many games? My guess is that BeamNG Drive wouldn't like SLI very much.

At least, he will have one GTX 770, that's not a bad GPU. It's actually pretty nice.

 

I haven't encountered any situation in which a game/application would crash & burn because I'm running SLI. Although interestingly, in some programs, it shows up as me having a GT630 SLI. (I have a 630 to power my non-gaming screens). SLI has really been great to me. This is my first SLI setup (580's), and I'm ready to move on to better ones.

 

SSD does absolutely ZERO for fps in games, they also do absolutely ZERO in everything else apart from the time it takes to retrieve a file from storage or improving the performance of the windows page file (which if you have enough ram shouldn't ever be used). They do absolutely nothing for actual computational performance, only improve how long it takes to get the texture for a tyre from the hard drive or locate your lovely word document you have been working on for 3 months.

 

Not quite. It actually has a huge effect on stuttering/etc on games that are constantly loading files from the HDD to store in your vram(Arma 2 and 3 are good examples of this).

 

Then you haven't experienced getting "long lags" because of the HDD. Average FPS, they contribute with nothing. Max FPS, nothing. But an SSD could potentially improve min FPS. And most important off all, you won't get those hangs. All of this is not true in every game, and I never said that.

Um, have you actually tried switching between HDD's and SSD in the same system? The difference is night and day! There are a lot of small files beging written/read when you use your computer. And when opening folders, programs, using programs, it's feels a million times snappier. You just can't compare it to an HDD. Have you ever tried, with a system HDD, scanning your system for viruses while doing something else (ie. multitasking)? Rebooting a computer with an SSD?

They don't compare, at all. HDD's should not be used as system drive. Period.

 

I am studying for a computer science degree, I have built several machines, I fully understand the intracacies of what a SSD does and does not do. It stores files with higher access speeds than a magnetic drive. A well coded software application should not be repeatedly buffering onto the drive and back, if anything it would indicate that you have either run out of RAM and are page filing (anyone with 8gb or more when gaming should never hit this situation) or the software is poorly written. One would never copy directly from storage to VRam either, you would copy from storage to system RAM and from system RAM to VRam. Once a particular object is in system ram *once* it should not be reloaded for each instance of that object, say a barrel, therefore it should not be stuttering mid way through the level.

A well written software application should have ZERO effect from whether it is running from SSD or HDD with the exception of content loads, which should occur once and only once for each piece of content (per level in a game). A few large open world games may by necessity need to load extra level content during gameplay, I am yet to ever have any staggering from this on a HDD (ARMA may fit into this category, depends on if they "chunk" the levels into smaller ones, easiest seen on minecraft but many games such as skyrim and Just cause do this too just on a different level to minecraft).



Oh yes, I have experienced long lags from the hard disk drive, but not during normal gameplay. Only when screen recording as a hard disk (and ssd too actually) can only read *or* write at the same time and I was trying to fly a jet on just cause 2 so it was attempting to load new map data. As soon as I bailed from the jet and stepped onto the ground it was fine, even so the game was playable. I have since set the target file for the screen recorder onto an old 80gb hard disk (one of the first SATA devices released its that old) and it was perfectly fine...
Also, I use windows 8, system boot time is already faster than windows 7 on a friends SSD equipped PC.
