Slowdown

When ever I look at the station my framerate plumets from 100 to 50-60. This is only when I look at the station even if there is no train in it. I even went and did simple station and turned the station off and it still does it. No matter where else I look I am at 100fps. This problem just appeared recently.

My PC is: Core 2 Duo @ 2.8GHz, ATI 4850 with 9.7 drivers, 4gb of ram, and monitor resolution of 1680x1050.

Also does No Limits support Crossfired GPU's?

If you look at break runs etc does this happens too?
try to check the boxes hide brakerun and hide transport in station settings, look what happens,
but im sure you wont notice the drop if don't look at the fps counter, if you do notice it,

any way are your gpu cooled enough? latest drivers? crossfire shouldn't be a problem unless you have the wrong drivers

I was asking about crossfire because I will be getting another 4850 soon. Yes, 9.7 are the newest drivers and the card doesn't heat up bad gets to around 50C on a full load so way in the acceptable temps.



EDIT WITH UPDATED SITUATION:
Forget my trouble, its my CPU. Its not gone bad its just a old CPU. An E4400, I had it overclocked to 2.8Ghz. I went and took the overclock off and realized it was 100% of my problem. When the OC is off I can't even reach 100fps and when I look at the station I get about 28fps. I need to upgrade my CPU.

Why worry about it if your frame rate is dropping to only 50-60? It is probably because nolimits is pretty old and is probably not that optimized for current hardware.

I know you problem. There is a fancy option in the NL Sim options called Vertical sync. You may have it off because you think it will improve performance, but it doesn nothing to your performance. The problem is is that NL says it is refresshing at 100FPS but it is not, because you monitor ( Unless a really new monitior ) And graphics card can't refresh at 100fps. There for when it has nothing to render ( When looking at the sky which is a moving picture ) it has nothing to render and therefor tells NL that it is refresshing at max speed because it isn't refresshing.

And then when you do look at something that needs rendered ( The station, track, brakes etc ) It realizes this and starts rendereing it in the refresh rate of you computer ( Most likely 60fps ) whish is why it drops. Your CPU is perfectly capable, but Turn Vertical sync on. It will keep the rehresh rate at the monitors max hz ( FPS ) unless you kill it with to many 3ds and then your GPU and CPU have a hard time proccessing the Info and real time. Thought I might help.

^ ya vsync makes everything look gorgeous on my computer, even though it says im only getting like 50-60 fps, it actually looks sooooo much smoother than when vsync is off.

only 50 fps? at the most i have 40! most of the time i have like 10 lol

When i look at the station my FPS stays at 100.

Good thing too. Never get sick of a lookin' at a nice smooth scene of that station...

Does anyone know exactly what Vsync does?

Vsync synchronises the FPS with your monitor's refresh rate To reduce the tearing and make the game or application run smoother, if you turn vsync on you fps won't rises above 60 but it looks much smoother than if its turned off

Merci Bouecoup! Thats kind of what I was trying to get accross, but it still explains most of his problems.

Hmm, well apparently I didn't have VSync on either, but I've never had a FPS rate problems. After turning it on, the rate drops from 60 to 30 or so when looking at the station, but it doesn't really change anything that I can see with the naked eye. More than likely it would be my screen resolution, since I can't go above 800x600. If I do, it runs, but I can't see anything and it's a *itch to close the sim.

Is an NEC MultiSync LCD 1850e XtraView out of date, or would having a Pentium 4 CPU, ATI Radeon x9200 and 768 Memory just not enough to display NL properly?

Sorry for the question, it is kind of out of place.

I would say you Stats, my comp isn't much better, and My current project runs at 1fps in the sim ( YES 1FPS ( I actually think it is worse because NL can't go to .2 FPS ) Anyway, V sync keeps your GPU from working to hard when it doesn't need to.

You should be able to run it with out problems at a playable FPS @low settings, are you sure you have the latest drivers? and have you checked your system for spyware and virusses?

Vsync doesnt take any load from your GPU, it "locks" your FPS at your refresh rate to make it look smoother,
Down side is that if you get less fps than your refreshrate it's better tot turn it off, It only makes the frame drops/lag look even worse

In short: If you got high FPS: Vsync=on, Low FPS: Vsync=off

Its just weird that all of a sudden it started running slower, just a month ago I could look at the station and get 100fps. I even tried it on a clean install....

I wouldnt make a problem of this unless you really notice the framedrop, personally i think you can't see a drop of 100-60 because already explained reasons involvingrefresh rates etc.

if you suddenly get drops to 20-30 youll should look for any problems in your hardware/software.
Like i already said, look for spyware and/or virusses, drivers, have you installed new software around the time this start happening?
other games where something like this is happening(visible lag)??

The weird thing is I can turn all the settings down as low as they go and I still hit a bad framerate when I look at the station.

Amen.

Well when your in the layout of a ride and it turns towards the station and it gets choppy...

i don't know about stations, but when I run a simulation that has a lot of trees, my framerate plummets, and it gets kind of laggy

nothing else does it, just trees... it could have a million 3ds objects and run fine, but if there's a lot of trees, then it sucks

its's actually kind of funny XD

stoof
