Framerates - System Upgrade?

[skylane]

Hello!

I have had framerate problems with my computer for a long time, now I am finally fed up and want to do something about it.
Unfortunately I don´t know enough about computers, so I hope that someone with a better understanding can give me some advice.

The symptoms look like this: a CFS2 mission starts out fine, but after a while, after the action starts the framerates slow to a slideshow, so bad that even controlling the aircraft becomes difficult.
This happens with missions that have a lot of aircraft, flak, fires on the ground after bombs have been dropped, etc. Also, if many of the newer (and good-looking) ships by Usio and the VN are involved, the outcome tends to be the same. Simple missions run fine.

I have the following system:
2,8 GHz, 2 CPUs
1022 MB RAM
Nivida Geforce 6200 Video, 512 MB

Could it be that this is just not enough to run CFS2 properly?

I noticed a recent thread here about the Vietnam project, where Dirtman recommended a 1GB video card and 3 GB RAM (what does DDR2 mean?) as a minimum for the upcoming Vietnam campaignsto run acceptably

Is it possible, and does it make sense, to upgrade an existing computer to these specifications, or is it better to buy something new outright?

Or could there be another reason for the framerate loss?

Thanks for any advice!

That's more than enough to run CFS2. Remember the game was released when computers were a lot less powerful than now. Try clearing out (search the CFS2 main folder and delete) your cdps. Make sure the display graphics settings (page one) are right for your computer. If these fail, try reducing the graphics slider to 5 instead of 6. If that works, then your computer wants a stronger graphics card for most any game.

Note: years ago I tried "Blades" explosion effects on my Win ME system, which was pretty good for the time... They overwhelmed my graphics display much like you describe. Are you using them perchance?

Skylane,

One thing to ask and look for is...do any of your planes have exhaust effects? These are bona fide framerate killers, especially in missions, not just for player aircraft, but also for AIs.

Second, you might want to check and ensure that all your mission-used aircraft are multi-lod.

Lastly, I've found that the stock effects are the best in terms of framerates. The "souped up" fire effects and other goodies tend to get you into trouble that way.

[skylane]

Thanks for your suggestions, guys!

Rami, I usually don´t use exhaust effects, and the aircraft I use are Multi Lod.
I do use some non-stock effects, though.

SW, I indeed have the Blade effects.. Now, how do I get rid of them if I want to have the stock explosions again?
Reducing the graphics slider to 5 helped somewhat in the one mission I tried, but it is still not acceptable. Does this point to a more powerful graphics card?
Btw, are graphics- and video cards the same or two different things?

Thanks for your suggestions, guys!

...Btw, are graphics- and video cards the same or two different things?

I meant the same thing... video card

You should be able to get the stock effects you didn't back them up?) from the disc. If push comes to shove, I can zip up my effects folder _- it is less than 1 mb - and send it to you. It contains some additional effects and a few slightly modified stock effects, but it won;t hurt anything. For example effects for Usio's ships and Nanni's extended wakes, oil slicks etc. that won't show unless you install his cfg's and dp's http://web.tiscali.it/Nanni/CFS/

Hi to all !

...you might want to check and ensure that all your mission-used aircraft are multi-lod.

How do you check that ? except trying them like I do,flying ,moving ,removing them,in my very sensible poor laptop.
I've noticed that sometime only one object plane or ship can slow down the fps.
Does exist a tool than can check if the plane ,ship ,object is multi lod ? or a way by disassembling the bgl to find the lod lines and chapters in the scasm?

How does cleaning out the CDPs help? Don't they have a function and don't they regenerate when CFS2 starts (or am I confusing these files with others)?

CDPs are files that record the damage to game objects as they are used. They sometimes build up and slow down the game and changes made, like to the dp of a plane. won't take until the cdp is deleted. Don't wory, the game generates new ones for each object as it is used --- planes, ships buildings... even trees have cdps.

Deleting them regularly gives you a "fresh" game and less for the computer to 'read', thus leaving more computer power for graphics generation..

Jean bomber,

I have a program that can check it...if you guys have a question I can analyze a model for you. This program is called Aircraft Container Manager.

As you can see...the Spitfire XIV by Paul Rebuffat has 5 levels of detail in the model, so it is quite frame-rate friendly, even in large numbers. As a general rule, dedicated CFS2 models tend to be multi-lod, but FS 2002 and 2004 conversions (except in occasional circumstances, such as the Junkers Ju-52) are single-lod, so using them in medium to large numbers causes major frame rate issues.

To summarize about LODs...

A CFS2 plane/ship/object which is multi-lod has multiple levels of detail, so that if a plane/ship/object is not VERY close to you, it will be drawn in progressively less detail the further away it is, thus increasing the PC's ability to draw it quickly, many times a second. This is especially important in furballs / bomber escorts, etc.

A CFS2 plane/ship/object which is single-lod is being drawn "full tilt" no matter how close or far away it might be. As you can imagine, this is problematic.

The easiest thing to do is add at least 1GB of RAM, - 2GB if your motherboard will accept it.
I assume you are using WinXP - it will use up to 3GB but no more (without tweaking the system)

This will wake your PC right up & you'll be surprised at how much faster it will run!

You will need to first identify what type of RAM your PC uses: use "Everest" - to tell you all about your PC.

Freeware, get it here: http://www.filehippo.com/download_everest_home/

Give me the make & model number of your PC & I'll have a look around.




- what does DDR2 mean?

It designates what style of RAM the PC uses:

DDR = Dual Data Rate

DDR2 DDR - 2 channels

DDR3 DDR - 3 channels

I have used Baldes effects infact I helped test them way back. I have used them on most likely the slowest pc anywhere and they never gave me any problems.On my new pc I found that I had to do some adjusting to the graphics philters. once I did that I went from 55 Frames persec. to 77 pharmes persec.

...A CFS2 plane/ship/object which is single-lod is being drawn "full tilt" no matter how close or far away it might be. As you can imagine, this is problematic.

...the exceptions to this would be single-LOD models designed with adequate detail in low poly counts. These low poly designs can do as well or better than some MLOD designs and yet look great doing it. The key word here is "adequate detail".

Most single-LOD conversions are drawn to the highest detail for the satisfaction of FS fans -- especially in the VC layout and external/internal animations -- and hence tend to have the highest poly counts allowable by the design programs used. In many cases, the extra animations also require that extra parts be drawn which add to the poly load. SLOD designs with low to mid polys can be pretty good performers - in numbers - within CFS2.

Always a valid point, Bearcat. Some single-lods can be used if they're configured for low detail. It's those high-res conversions that kill ya!

Many thanks to all of you who offered their opinions!

I will try different effects, but in the end I believe that upgrading my computer will be the best option.

Dirtman, I do have Windows XP. Is the information in the pictures useful for you?
Do you think that adding more RAM will be enough, or would you suggest to also change the video card?

Whether you upgrade the vital components or just go all out for a new rig, you can never have too much punch if you're a hardcore simmer-gamer.

In terms of just upgrading parts on a tight budget, your dual core processor running at 2.8Ghz w/o overclocking should be sufficient. But a slight overclocking wouldn't hurt, if you were an advanced user. Sloppy overclocking can lead to system instability and CPU damage. But you could certainly use a boost in memory (the suggested 3 Gb is good) and a newer vcard -- maybe something in the Nvidia GTS series with about 1 Gb memory.

On my XP-Win7 platform, my i7 930 quad core runs at the default 2.8 Ghz but it feels more like 3.5 Ghz because i have a GTS 250 vcard w/ 1Gb and huge speed-adjustable fan, 4 Gb of Corsair DDR3 memory, a 750 watt PSU and five cooling fans in the case plus a killer heatsink fan. My virtual memory cache is manually managed at 2 Gb minimum and 4 Gb max. I was overclocking the CPU @ 3.4 Ghz but since the total system configuration performs so well at the default processor speed, i decided to back it down to the default speed for processor longevity.

Buying newer and better is great if you're a hardware novice with deep pockets -- you can reach your destination quickly with fewer problems and less study. But building a better rig is so much better for advancing your knowledge and keeping your costs down. However, you have to be patient, committed and willing to put in the time to acquire the right knowledge. There's a virtual ocean of resources in cyberworld to keep you informed, and as always, Google search is you best ally.
