What is causing the low fps?

[ComradeHX]

On PR 909, my PC gets okay fps on only one map: Asad Khal(1km) - ranges from 27-46fps.

Every other map, I lag unless I look at the ground or sky.

Is this due to my lack of RAM(currently have 1gb) or other things(I have a Nvidia Geforce 8400GS and a Pentium 4 2.65ghz single core POS CPU)?

I am trying to spend the least amount of money to make PR playable(I do not play any other 3d games... I mainly play Japanese Visual Novels and watch anime on my PC), please help.

Btw, there is very little change in fps(or nothing at all) when I decreased everyting to low/off.

i have seen that effect as well, seems to be when the system is hitting its limits

"Resource Monitor" (built into vista and win7) will give you an insight on where the bottleneck is (1GB is pretty damn low )

check if the lag is syncronous to your HDD activity indicator LED - that means alot of access to the disk is causing the probem (loading textures etc) - probably due to excessive usage of the pagefile

[ComradeHX]

CPU usage is around 50-60%

I guess it is still the RAM.

[General_J0k3r]

1 GB of RAM should definitely be a bottleneck. needs moar RAMz

[weixman]

Well i have 768MB of ram and it works pretty much fine

[JacktheStripper]

i have a q6600 quad core, 4 gigs of ram and a 9600gt 1gig and i do FPS lag on some maps, especially scoping in and out of rifles, i think it may just be a texture in the map which is inefficient and causing lag?
and yes i would buy another gig of ram, its cheap enough

For me, scoping in actually increase 10fps or more... lol.

Thanks everyone, I will try RAM first.

One more thing: is a RAM extension PCI board going to work as well as just RAM plugger into the Mobo?

Scoping also improve fps for me xD

I have this system ( CPU : Athlon 4400 X2 , GPU : Geforce 8600 GT , 3GBs RAMS , Win7 ) and the game still lags even with lowest graphics + view distance 75%. My framerate is between 5 and 50 fps. I guess that with 1GB you will lag. And the other guy who has 768MB rams , I don't know how you can play with that xD

Yeah, its odd. On some maps ( iron ridge, yamalia and some more ) i have serious lag and low fps, but i still can play other maps with no problem. Map loading times are huge though (3 to 5 min)

[obZen]

There is a memory leak. I have 4GB of ram and certain times it's going up to 1.5GB for BF2...I play newer and much more demanding games that don't go this high.

That is just a pci drive using ram sticks instead of physical drives. Its super quick but not useful unless u want the speed for a reason. It does not extend the amount of RAM your mobo can handle.

I was getting down to 38fps at times in some of the forested maps and maps with dense vegetation. After a proper install of the latest Nvidia driver I did notice a performance increase. Now instead of dipping to 40fps'ish, it's only going down to the 60's.

Settings I tested were played on map Beirut-
NV-Control Panel: 1400x900@75Hz, 4xAA(Nvidia override control)*, 16xAF, 'Single display performance mode', AF Sampling Optimization = off, High Quality IQ, Trilinear Optimization = off, Vsync = Force Off
Game settings: Terrain = Medium, Effects = High, Geometry = High, Texture = Medium, Lighting = High, Dynamic Shadow & Lighting = Off, AA = Nvidia Override Control, Texture Filter = High, View Distance 100%.

-58FPS low, 168FPS high, 113FPS average on my machine in Beirut... I will get averages form other maps*

Go get those drivers, they seem to make a big improvement!

EDIT: *Wrong settings, edit for misrepresentation of settings. I had found this out later when I went back to my 'Nvidia Control Panel'.

To get your 'average' frame rate in PR, since there is now BF2 benching tool, you're going to have to do a little math... But it's simple!

First, after you've entered a populated server bring up your console("~" key for most people) and type the command "renderer.drawfps 1"(do not add quotation marks) and hit enter. In the top left hand corner will be your frame rate counter.

Second, you will want to administer this and record your 'noticed' Lowest frame count and your Highest frame count. Looking around at complex textures should help with decreasing your framerate, as well as looking over large landscapes without a scope or binoculars!

Next, after you have your 'Low FPS' and 'High FPS' numbers you will need to add the two numbers together, than divide the sum by 2. This will give you your machines average frame rate with the BF2 engine.
(Low+High)/2=Average Frames Per-Second

You will than have your average frame rate your 'settings' are giving you. You can use this math to see if your settings are making your framerates go up or down.

------

You could use this calculation to see how much frame rate decrease is associated with Net-lag. Create a server on a separate machine in your house and enter the server alone, then apply the above guide. After you have compiled the averages of online and offline gameplay, the difference between the two will be the amount of frames that the Netcode of BF2 decreases because of variances in/during online play.

I myself have not yet tested the 'averages of online and offline play' method, I read both of these guides in different forums and decided it need to be posted here. Hopefully this info is useful to someone?

Hope this helps!

(Low+High)/2=Average Frames Per-Second

That gives you the Median Frame Rate.

Not the average. You could easily have a consistently high FPS and have one or 2 low spikes and completely ruin that calculation.

hey about those nvidia 196.75 drivers: i was excited with your claim so i went to nvidia to get em. however they are not there anymore, so i searched google for them and found this:

NVIDIA pulls 196.75 driver amid reports it's frying graphics cards -- Engadget

guess ill wait for the next one XD

[Valleyforge3946]

Well.. OP. you need more ram.. yes.. there is a memory lea and it causes bf2 to EAT memory. i have 5 Gigs of ram. and i have seen PR use 2.1 gb's of ram before. its not uncommon. i have a GT250 and play at 1440x900 maxed and i get a lot of lag sometimes.. i drop from 75fps to 17 in the city. Lol. when i scope in on ANYTHING, my FPS instantly doubles. AT LEAST.

[Pedz]

I dont know why you guys are still using 195 nvidia drivers when they're on iteration 270..
270.61 out today.
