Extreme Lag issues with HD 7750 ( Please HELP! )

Sorry for the wall of text.

I bought a Sapphire HD 7750 today to replace my old 9500GT. After the swap I installed all the drivers and catalyst control center stuff from the AMD website. When I tested out blacklight: retribution with all the graphic options set to maximum at my native resolution of 1440x900 , i got a framerate in the single digits.(Not surprising.). I kept turning off all the options to find a playable framerate. Even after turning off all the options and setting everything to the bare minimum the game continued to lag. When I set the LOD of everything at medium , while walking straight in multiplayer FRAPS showed the framerate in the 40's but the second I turn my head in the game , the framerate drops to the single digits and the screen freezes for around 200 milliseconds.The same thing happened in the solo training part , but the effect wasn't quite as pronounced.Somehow this card manages to be worse than my 9500GT at the lowest settings which at the very least gave me playable framerates with a few hiccups here and there.I installed the beta drivers from AMD's site , so there might be something going on with that.The same thing in Team Fortress 2 happened , a lot more lag than my previous card with slightly higher settings.

My Specs-:
CPU-: Core 2 duo E8400@3.00Ghz.(CPU bottleneck perhaps, though the fact that its doing worse than my previous card means that its not likely.)
RAM-:4GB DDR2 RAM.
MOBO-: Generic INTEL DG31PR.

Did you uninstall the nvidia display driver before install the new card?

Download driversweeper, uninstall all GPU drivers, run driversweeper (GPU drivers only) in Windows Safe Mode, reboot, reinstall AMD drivers.

Yes , I uninstalled the driver , then removed the card , booted up in safe mode and ran driver fusion and removed all the remaining registry entries apart from a few because I didn't have the premium version.

But now that you mention drivers , I remember that I first downloaded the drivers from Sapphire's website and installed all of them. Before rebooting I visited AMD's website and saw that Sapphire's drivers were old , so I downloaded all of them from AMD and installed them and rebooted.

I am also using an adapter from DVI-I to VGA.

I am also seeing some innocuous artifact like flickering on the taskbar only when I launch google chrome.Also Chrome seems to be crashing a lot now.

simple answer - replace that gpu
April 8, 2013 9:36:30 AM

I would recommend never using driver sweeper. Alway follow the method on overclock.net on how to manually delete all the amd driver stuff. Last time I used driver sweeper Windows wouldn't boot and I got to reinstall. If you run kombustor or another gpu benchmark do you see artifacting?
April 8, 2013 10:14:02 AM

I just tried reinstalling the drivers , but even now it is performing worse than my old card.To think I paid a 130 bucks for this.
April 8, 2013 10:29:28 AM

Run gpuz in game to record your max gpu usage. I have a feeling that your cpu is holding you back. I thought you said core 2 quad at first, but a core 2 duo is most likely a bottleneck.
April 8, 2013 10:55:51 AM

^lol cpu will not bottleneck at all.i think that gpu is faulty
April 8, 2013 10:58:21 AM

Best is to reinstall the windows.this works best
April 8, 2013 11:02:07 AM

lol, yeah but it will not bottleneck a meager 7750, reformat and reinstall and if that doesnt work return the gpu?

OP, what psu are you using?
April 8, 2013 11:16:16 AM

Has the OP tried other games ?
April 8, 2013 12:21:14 PM

The core 2 duo will be a giant bottleneck in skyrim, starcraft, wow, really anything that is cpu bound. ASHISH really had some bad advice here.

Do you even know what bottleneck means ? its if you pair a hi end gpu to a low end cpu. thats clearly not the case here. so the issue is not cpu bottleneck.OP must first try more games so that we have a clear picture of what's going on
April 8, 2013 1:21:37 PM

Which game were you playing exactly?
April 8, 2013 1:53:17 PM

no no no c2d will not bottleneck the measly 7750....
April 8, 2013 8:07:46 PM

Well , I guess I will try reinstalling windows as a last ditch effort.(OH! The horror!).
BTW what is the usual score for a HD 7750 on furmark's 720p benchmark.I got something around 560 and I have a feeling its a little low.

And to all those saying that my CPU is bottlenecking my GPU you should check out toms CPU hierarchy chart.You will find that it is ranked on par with AMD's phenom || X4 955.Also games are running worse than they did on MY OLD 9500GT. How does a bottleneck make sense?

The games I tried are -:
Blacklight Retribution.
Team Fortress 2.
Fallout 3.

Best solution

dude op has hd 7750,not hd 7970.i agree core 2 duo will not perform such great but,not that bad what you think.
e8400 with hd 7750 can handle most games fine with good fps and settings.first see op is getting lower fps than his old gt 9500 lol.op is playing blacklight: retribution in which core2 duo meets requirements

see real world performance with core 2duo

you guys just see the name"core 2 duo" or "pentium" and start saying bottleneck, bottleneck!

Everyone faces bottleneck.it is better to stop using that word 'bottleneck" as it is "Overused term" Nowadays


April 9, 2013 6:06:50 AM

wow these forums have really gone to crap
April 9, 2013 6:45:06 AM

I had a core 2 duo with a 260m and I know that cpu was a big bottleneck. In most games it wouldn't matter if I put the video settings on low or high the fps would be the same. That was definitely a bottleneck. This is the last reply I make: OP it is a cpu bottleneck. Watch the cpu usage and you will see it getting maxed out at 100%. Your gpu usage will also be under 100% because the cpu can't keep up.
April 9, 2013 7:05:40 AM

maybe overclocking might remove the bottleneck if at all there's one.
April 9, 2013 7:11:17 AM

Even its bottleneck,just think how can anyone get single digit fps eg - 5,6 or less than 10 in moderate(not much demanding game)????

may be nvidia drivers files in registry can be the cause as drivers doesnot completly uninstalls as traces of files remains in pc

In CPU bound games the C2D will choke down to single digits don't believe me then keep you old bottleneck CPU and play games like a slid show.


yes you are right,core 2 duo will not perform so good in cpu bound games no doubt there.

i am just saying that see op's situation - he is playing blacklight game which is not cpu intensive game,he should get good fps with high settings at his resolution.if he get single digit fps then it is clear it is not the issue of bottleneck and what he said he was getting more fps with his old 9500gt than hd 7750.
April 9, 2013 9:56:19 AM

Ashish is correct. His 7750 seems to be performing worse than his old 9500gt so his problem is a driver issue or faulty card not cpu bottleneck
April 12, 2013 11:39:09 PM

AHHHHHHH!!!! F*** THIS! Even after reinstalling windows , this card is somehow doing worse than my 9500gt at lower settings. Hopefully I can return this card. Thanks for your replies. I am never going back to AMD or sapphire after this.
April 13, 2013 2:10:54 AM

Don't blame AMD or Sapphire for this. Its your bad luck you got a faulty card so blame your luck not the card. Even Nvidia has faulty cards.

That's because Core 2 Duo is a major bottleneck and it's ridiculous that your false information even made it to a best answer selection being that is a completely wrong answer.

The OP had clearly mentioned in his OP that he is getting worse performance in the same game with his new 7750 compared to his old 9500GT. Even considering your point that Core 2 duo is a major bottleneck i cannot fathom how a better card will perform worse than older weaker card in the same game . its not like the OP is using a Pentium 4 or Athlon XP that the cpu will be such a bottleneck as to completely and utterly hold back the 7750. So your point is wrong and Ashish is right

Going from GTX 560SE to a 7850 which is a similar GPU performance upgrade as OPs BFBC2 performs worse on my rig because as it were games favor either nvidia or AMD. Blacklight must like nvidia cards but i have to say I was getting major CPU bottlenecking in that game with a Phenom II x4 970 OCed.


said:

The 9500GT is comaprable to a 5570. 7750 is atleast twice as powerful as that maybe three times as powerful.
Also CPU bottlenecking does not work in the way you described. Even at its worst, the frame rate obtained by the new card even due to severe cpu bottlenecking will be the same compared to older weaker card, not lower.
Getting lower fps is a sign of faulty card not bottlkecking. what bottlenecking would instead have done is get the same fps as before or slightly better than before not lower. and why do you think faulty card or driver issue might not be the problem ?

I to am having similar problems with sapphire 7750 framerates dropping to nothing then game freezes. I had GPU-Z running and my core would drop to idle, so was wondering if it's a power management problem.
June 13, 2013 6:15:54 PM

What idiots man.. Ashish had it right. There's no fricking way that a HD7750 would bottleneck a core 2 duo e8400. Its not that the HD7750 is an INSANELY fast card or something and that E8400 isn't a measly processor either -_- no bottleneck just a faulty card

Thanks for helping to buyers.
