Win 7 Extreme drop in FPS

[BloodBane611]

I stopped playing for 3 or 4 days, when I tried to start playing again yesterday I was was having extremely low FPS, displaying as 15 (ie minimum) in PR most of the time. Prior to this I had no lag issues at all, now every map completely lags out for me in certain areas, especially areas with high numbers of statics.

I've done a complete reinstall of BF2/PR, and picked up the latest drivers for my gfx card, not really sure where I should go next.

Gonna take a wild guess and say windows 7 is using a lot more memory.

Could do with system specs really.

If it's a sudden change and you're one of the few v0.9 worked for then it could well be a case of wiping your shaders in MyDocs, especially if you've been playing other BF2 mods.

Other than that it could be the now infamous 0.9 lag that a lot of people are experiencing and reducing textures to medium can help. If you have Crossfire / SLi, some "X2" version of a card I believe you're screwed and the lag is random owing to dodgy memory allocation, reducing settings to lower memory usage is the only solution of sorts.

Err... It used to work amazing with no changes. Windows 7 uses about 800 mbs for me, I don't know why everyone always brings up windows as the problem.

It's not a shader problem, I removed user profiles when I uninstalled/reinstalled BF2, so the shaders got wiped with them. I'm running an 8600M GT, it was running beautifully earlier this week. Anyhow, I turned down the textures, which seemed to help a little bit, but turns out I still have very low FPS. It's displaying as 15 (minimum) in PR, even on maps I used to get 30+ on.

yeah specs would be nice...
a 8600M is an integrated card i am assuming you are running it on a laptop
i get my quality drivers from here: NVIDIA & Laptop News | Latest NVIDIA drivers and related news | laptopvideo2go.com

a sudden change in performance might indicate system instability
try reverting your system with system restore
run "chkdsk c: /r" and
run defrag
check in bios if settings are still ok - (shared memory for gfx, ram speed, clock rates)


after reinstalling nvidia drivers it sometimes resets settings - check if its still configured correctly (e.g. changed from performance mode to High quality mode)

i like to blame punkbuster alot - try to manually reinstall it

leave the pc up and running over night so it can finish its indexing and what else win7 likes to do

ofc - scan for viruses
check your background processes

did you loading times increase too?

there is something def wrong with the code.

my specs: intel e8500
geforce 285 gtx
4gb ddr2 ram
1tb 7200 sata drive
windows xp
latest drivers

vanilla BF2, any map, anything on screen
at 1920x1080 all settings max, 2x AA never dips below 100fps

PR 0.87
1920x1080 all settings max, no AA. lowest fps (damn fallujah) was about 40 something

PR 0.9
1920x1080 light, textures, geometries mid, rest high no AA lowest is 32 fps
1920x1080 all settings low..... lowest fps 40..... wtf
1600x900 light,texts,gemo mid rest high no AA lowest 34 fps...

heck i tried moving view distance which i never touch under any circumstance... gained 5fps... =/

cannot find any setting to move, to actually get decent all around fps, tried changing drivers... everything else, defrags, paging etc nothing at all. sometihng is choking the bf2 engine

BTW, with my laptop, i used to have a degrading performance over time, found out it was actually dust that made my GPU's temp rise and thus trottle down... give it a good cleaning, if its compressed air, make sure you hold the fan still or you could damage it by making it spin too fast

[turnpipe]

There it is, its getting hot.
Get a desktop.

Okay, turns out it most likely is overheating. After allowing the computer to cool down all the way (shutdown for 10-15 minutes, casing feels room temperature) I've started it up and played PR, with FPS decreasing as the temperature of the computer increases.

[[R-COM]SnipingCoward]

remove the side panel to allow more air to get in, see if the problem still persists

dedusting the fans and coolers, between drives definitly helps

if you know how to - you can renew the cooling liquid between coolers and chips (i.e. CPU, GFX chip, Nbridge and what not)
one time I was removing the cooler off my NB-chip and saw that the cooling liquid got burnt -> bad - the mobo was already severely damaged and i had to replace it

have a look at the mainboard and cards and see if capacitors are leaking, bloating or rusting (http://www.mad-monkey.co.uk/resource.../capacitor.jpg) this means grave system failure is imminent and the part needs to be replaced ASAP

getting new or optimized gfx drivers can help you with heating problems
