Hi everybody, I'm getting a feeling that I screwed myself up pretty bad. Let me clarify.

About 3 weeks ago I got I purchased new components for a new PC built. I'm reusing CD burner and tower only. Running Win7 64bit and backup OS - XP SP2, 4gb 1066 ram, Intel e6300, WD 640GB SataII 32mb cache, 630W PS.

I got GTX 260 OC 896MB by MSI (link if you care to see it). The card has PCI-E 2.0 x16. My new video card arrived 5-6 days ago, but just today I got around gaming with it for the first time.

I noticed that games like COD4 which is over 2 years old game runs kind of slow and with serious lag sometimes. I can't say that I like the performance that the card delivers right now. Batman Arkham Asylum also has some lag at different moments. I do NOT think that the card is bad though.

I thought, it might be driver issue, but nobody really have complained from the new nvidia driver (191.07).

I took a closer look a my MBoard (link here) and it turns out it is PCI-E 1.0 x16 only!!!!!, NOT PCI-E 2.0 x16.

Is it possible such serious a lag in gaming to be due to my board PCI-E 1.0 bandwidth?

Is my MBoard limiting my video card's full potential?


The good news for right now are that I can still return the Mobo and exchange it for PCI-E 2.0 x16 compatible.

Should I do that? Should I change the Mobo while I can?

I will appreciate your comments and suggestions.

OK PCI Express 1.0 and 2.0 are totally compatable.....I am pretty sure even a 260 will not use the full bandwidth of a 1.0 slot.
As far as motherboards go that one will work but if you can afford it go with a P45 chipset for the best overclocking. I like the Gigabyte EP45-UD3x series.
Most likely that E-6300 at stock speed is whats holding you back.

try that new mobo with pc 2.0 if you still can and oc your proc to 3.0...also before that delete your new drivers and install some previous drivers... also check does your gtx 260 get all power from the PSU...what brand is your psu too

"Worst FKin Idea EVER !!

Either wait for the HD5850 series to come down a bit or else get and HD4890, but adding a second GF9800GTX is plain stupid, especially heading forward.

But to the OP, did you bother checking the Champions forum first?

You're not the first person I've heard this from and low and behold there's a mega thread at the online site about the lag;

http://forums.champions-online.com [...] hp?t=35438

and some advice about rolling back the nV drivers to imrpove performance where alot of lag was introduced with the latest driver update;

http://forums.champions-online.com [...] count=1184
http://forums.champions-online.com [...] count=1186

So don't buy a new card, and definitely don't F'in buy another GF9, see if rolling back the drivers helps and then maybe check the thread for updates. "

its the driver lag so better roll back

I just read somewhere that pcie 1.0 x16 allows 250mb/s bandwidth vs 500mb per sec for pcie 2.0 x16. Isn't that thr issue here?

Somebody asked about my PSU. It is Rosewill Green 630W.

I dont think i should be getting lag with gtx260 OC on COD4 default settings and 1280 screen size. By default setting ,pretty much everything is maxed out.

I got sandra installed. Which test should i run regarding the issue? Bunch of test for VGA there

The 250 and 500 mb/s are right .......however the cards themselves are not using all that. Its like the SATA standards for hard drives. Extra bandwidth available but not necessarily used.

Rosewill PSUs are not known as high quality. You need to make sure it has enough amps on the 12v rail to run the 260.

(Minimum recommended power supply with +12 Volt current rating of 36 Amp Amps.)
Two available 6-pin Molex hard drive power dongles

That is for an EVGA (nonoverclocked) card http://www.newegg.com/Product/Product.aspx?Item=N82E16814130434
Likely thats pushing it for that Rosewill.
I would upgrade to something like this http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004


John__ you a little confused as to where to answer what? And I have to say ive never heard of the Champions forum myself.

my system utility program is showing me 12.35V. I don't think PSU is problematic. Windows Task Manager shows above 90% CPU usage during gaming with COD4. Maybe CPU is bottle-necking it. Not quite sure though.

Currently i play in xp sp2 because the game crashes in win7 during initial videos.
It is impossible to play even intro. I play batman arkham asylum in win7 and at some points it is choppy there too. COD4 in xp is worse (maybe because of the open sufraces),than batman in win7

Rockyjohn, i just realized what you were asking me.
I guess i can put pretty high dollar CPU in it. Dont want to spend the money though. When i was getting it that CPU i was thinking is potent enough.

Here are the charts comparing select Core 2 processors. It would seem that the e6300, while slower than the others listed - should not be a major problem. What game settings are you using - AA and AF?

http://www.tomshardware.com/charts/desktop-cpu-charts-q3-2008/compare,821.html?prod%5B2182%5D=on&prod%5B2194%5D=on&prod%5B2185%5D=on&prod%5B2202%5D=on

Try overclocking and see if your gaming fps improves. That would be the best indicator if it is a cpu related problem. Are you using the stock HSF or did you upgrade it?

Right now, AA is 4x, AF (is a slider) so about 25%., res. 1680x 1050

Optimal defaults does not improve much the choppiness

What does HSF abbreviation stands for.

HSF = heat sink fan - the fan assembly on top of CPU to dissipate heat. The one that comes boxed with the CPU should be good for a mild OC but a more significant one will create more heat in the CPU requiring a better HSF to dissipate it.

Very strange.

Are all power saver modes on pc and monitor turned off?
Have you tried rolling back to an older driver?
Reseating the video card? Checking both power connectors to the video card?
Testing with another graphics card (even a slower one if that is all that is available)?
Did you run memtest (for at least 8 hours) and prime95 to test system?
What about performance in other games?

+1

Also check the graphics cards and cpu temps.
 
Pentium Dual-Core E6300 isnt exactly a high end cpu, and it is a dual core so dont expect epic performance

My mates E6850 + GTX260 rig in the new batman lags between areas etc from time to time but plays it aok

Do a 3DMark run and give us the numbers and see if someone can compare the scores

Hey everyone. I got some testing done today and would like to share results with you.

First off, I had prime95 running 1 test for 2,5 hours and couple 30min tests with no problem. CPU temps went to 62C for few secs but they averaged at around 58-59C i think.

I noticed that my CPU downclocks to 1600Mhz(267MHz x 6.0) when idling. Wondering if that is not something to be looked at.
Same happens with the video card too.

Second, I got 3DMark test done. The result is quite astonishing for me. test 1- 6080 point, test 2 - 6011 points(while listening to music).

See >>screenshot here<<

There is apparently something seriously messed up here. People with similar CPU & Video cards are getting atleeeeeast over 12000.

I don't where to look at. :sweat:

my specs are:
ASUS KPL-CM G31 mobo
MSI GTX 260 896mb O.C.
Intel Dual-core e6300 @2.8Ghz (NOT core 2 duo)
Western Digital 640Gb SataII drive
Hitachi 80Gb SataI drive
Rosewill Green series 630W PSU

all stock fans


I'm going to try my old XFX geforce 6600GT. if it works with this board I bet y'all I'll get more that 6080points......terrible situation and I'm running out of time soon.

You might also open Windows Task Manager (Control - Alt - Delete) and select the performance tab. It should show CPU usagae history for two separate cores. Leave this open and see if both are running near 100% while playing game - especially when system lags - and separately for comparison running a short prime95 test.

The CPU downclocking while idling is part of the energy saver feature and is normal. Hopefully it is not doing that while playing a game.

When you installed your video card, did you turn off the onboard video and uninstall the drivers according to your the instructions in your mobo manual before installing the new card and drivers? You indicated that you were using the new nVidia drivers and had not seen or read about any problems with them. You could try rolling back to an older driver - maybe the one that came on the disc with the video card.

I am sorry you are having such a difficult problem and no one has been able to help diagnose it. And unfortunately westill have not isolated the problem - could be weak or bad CPU or bad graphics card, or something else. Its a long shot, but you might try running the full system test at PC Pitstop to see if it reveals anything. Beyond that have you may need to run some of the Sandra tests to check out specific components.

Thanks for the quick response rockyjohn.

During game play (COD4) cpu is at 70-80% i thing. I don't thing it goes above that.

Yes I did turn off onboard VGA in BIOS. Every time I am to install new video driver I uninstall the previous one and restart if requested.

I did use 185.85 instead of 191.07 but nothing changed. Now I'm back with 191.07 downloaded from nvidia.com



I have though, an UPDATE. I just ran 3Dmark test with my XFX nvidia 6600GT. The score seems terrible again: 513points. (well I was wrong about beating gtx260's score)

See >> screenshot here <<


According to the scores, seems that gtx260 performs 200-270% less that what it is capable of (6080 vs ~15000points).
Again, according to the scores XFX 6600GT performs atleast 330% less that what others have as score (513 vs ~ 1700points).

I thing I should scratch the scenario of bad video card, bad power supplied, bad connectors.

Interestingly, during tests with both cards, CPU performs almost identical (with gtx260: 2530points and with 6600GT: 2384points).

Is it possible my older hard drive (sataI) which is now primary with XP to be problematic? I'm just shooting in random directions here.

Ideas? Suggestions?
