lo fraps and main memory use

[rrbobby]

I have a quad core with 8 gigs and a geforce gtx 470 with 1280mb memory.
when trainz is running, 1.62 gigs main memory is used. When not running 1.26 gigs are used. can't trainz use more than .4 gigs? would using more main memory improve the fraps? can trainz be made to use more. I got little improvement going to the 470 from geforce 9600gt 512. Im disapointed. Any suggestions.
Thanks. rrbobby.

What is your resource cache setting under options (advanced). It is my understanding that 50% of ram is recommended.

The max allowed is where it is set, 2048, I don't know what the units are. I can't make it more. If you know of a way to put in more please let me know.
Thanks much. rrbobby.

2048 is the max as far as I know. Have you tried adjusting the detail settings in surveyor? Sometimes that helps. Actually, what FPS are you getting. Anything over 25 in good for viewing.

I assume you have a 64 bit operating system such as Win 7 64 bit? TS2010 puts a bit more work down to the GPU which may help.

Thanks John

I'm inclined to think that this problem is nothing to do with memory use but maybe an EDR and a defrag required, memory use seems about normal and with that setup there should be reasonable if not good frame rates.

8GB and a GTS450 here and clearing 100fps plus in many places.

The only other things I can think of is that maybe the OP is using a route full of dodgy splines which is hitting the performance. Or possibly an underrated power supply for that GTX470?

Thanks for your response

My opp system is MS 7 64 bit with a 550 watt power supply. The lower frame rates, 15 or so, increases with fewer trains running. I had 60 fraps on a particular
simple layout, Tuckahoe jct with loops at each end for trains to come and go while I played tower opp. As I added the 3 RDC's the frames dropped but still above 24, the min. for smooth graphics. Then I added 2 freights with 1 eng & 30 cars each. That's when the fraps dropped sharply to 25 and below durring a pass with 2 or more trains. Looking in the direction of a couple trains behind sceenery
goes from 60 to 18 or 20 fraps. So it looks like the fraps go down as trains increase. A realistic 2 or 3 engine hauling 60 loadded coal train with 2 helpers brings the fraps down to 12 - 17, unwatchable. I just added the power supply and 470 with 8 gigs with no improvement.
Clam1952, what is EDR? One drive has just been defragged And the other is new. Sorry, I Don't under stand "the op is using a route full of dodgy splines".
I know what splines are. I tested my train slowing on a piece of strait track,
same result. 100 fraps, wow, thats what I expected. I spent a bundel on the
upgrade, 64 bit op, 8gigs mem & the GTS450. Something has to be wrong. I used the trainzoptions settings that came with ts2009. Can improvements be had
with different settings clam1952? What are yours? Maybe the answeres there.
Other wise I might as well sell the computer and start over.
thanks every one. Happy hollidays. rrbobby.

Trainzoptions.txt setting don't seem to do anything in 2010 here, other than slow it down if you add the -resourcememory line.

Should have thought of this first!
Are you using OpenGL by any chance? as it doesn't work very well with any of the newer Nvidia cards or ATI for that matter, frame rates are way down on DirectX and that may be the main problem, try DirectX if you haven't already.

My settings in Trainzoptions.txt are the default install.
EDR is an extended database repair, which you initiate from the File menu in Content Manager , be warned though it can take a long time and sometimes needs a second run as sometimes fixing one error seems to generate another one.
Options in Driver / surveyor are all sliders to the right, Anistropy 16.
In launcher options Antialiasing 4

May be you need to tweak the graphics card settings although I doubt that would cause drop in performance like that.

OP meaning original poster, dodgy splines meaning that many older splines do not work very well in 2009 or 2010. The solution is to either fix them by adding a line to the config that reads uncached_alphas 1 or change the format of the config file to the method used in 2010 or easier, replace with something else that isn't causing a problem.

The next question is obviously how do you tell? That can be done by enabling the performance stats in developer options in the Options menu.

There's a load of info that is displayed on the left hand side of the screen, what you need to look at is the line that says worst buffer count, anything under about 50 won't be a problem, anything over 100 will, the offending kuid is displayed on the same line, then its just a question of tracking down what and where it is. Adding the line -showkuids to trainzoptions.txt will display the kuid of any item selected in the bottom right corner, which makes it a bit easier.
Where it gets a bit tedious is when you clear one and then there is another high value over 100. The items are very often track, roads and fences, I had one fence that had a worst buffer count of over 600, couldn't even get a loco to appear in the area it was in let alone drive anything, fixing that it was a bit better but I still had other splines that were over 200 in the same area, fixed them and all was back to normal.

You are running in native mode? I don't think it is the default in TS2009.

Thanks John

thanks clam1952

Going to directx helped but multiple trains slows things the most, 13 fps, one train of reasonable length is ok but there is a general improvement for sure.
I kept trainzoptions default settings the same as install.
CM has ordered content repair and exicuted it a couple times.
I used your driver/surveyor settings.
I did not touch graphic card settings as I know nothing about them.
Performance is the same on older, 2006, and newer, 2009, layouts so splines
probably are not the problem.
I found no 'worst buffer count' kuid's above 50 on any layouts. All layouts totals were less than 500, most under 200 for the entire layout. The highest kuid was 12.
If you think of anything else at all please let me know. You are a great help, thanks.
Did you attend Trainz university? lol. You sure know a lot.
Thank you, rrbobby.
