New Hardware Runs Worse

Hey,

I've just upgraded my computer from:

256mb 6800GS to a 512mb 250GTS
2gb RAM to 3gb RAM.

I tried to play Crysis, which before was smooth when played but kept crashing, and it's really, really un-smooth. Almost slide show like.

I've formatted, installed all the latest drivers, checked all the wires, the graphics card has two seperate cables to it. V-Sync is off. Tried everything on low but still no luck.

I also tried Prototype but that is even worse, totally unplayable :o

My current spec is:

AMD64 3200+ @ 2.2ghz
3gb RAM
512mb 250GTS

Surely those are enough to play it on low?

Thanks.
 
installed the latest drivers?
gfx tend to do that when no proper drivers are installed i think :S

have you connected the 2 pciexpress power connections on the gfx?

Definately got the latest drivers off the nvidia website.

Which power connections? There is a cable going into the card with two cables coming off for power cables to go so I put them on seperate power connection wires.

Might be the cpu maybe? Now you've got a more powerful gpu the cpu will have to work harder to keep up with it and as its a single core that leaves less processing power for the game itself. Crysis is very intensive and likes a few cores unfortunately :/

By the way playing at low res, etc tends to just put more pressure on the cpu.

That is my exact PSU, the recommended for the graphics card is 450watt so its enough to run it surely?

Don't you have a PCI express power cable off your PSU?
You should have a connector on ur PSU that will connect straight to the graphics card without that connector...they tend to recommend setting it up that way, not the way you've done it.
I presumed there would also be 2 sockets on the gfx card but maybe theres only one
 
Tbh, if power to the graphics is an issue, it would tell you when you logged onto windows that its not getting enough power.

That 1gb of RAM extra you put in...
take it out.
leave it with the original 2 gb, then see what happens...
 
I'd go with the PSU not being powerful enough, you need to check the amps on the 12v rail not just the watts, requires 38a on the 12v rail I think. These cards are pretty hungry, I powered my 8800GTX no problems with my old Hiper 720w but wouldn't play ball with GTX260.
 
I'd say your problem is definitely CPU power, or rather, horrendous lack of it.

Crysis is very demanding with physics etc, and plenty benchmarks show higher frame rates from the same card when you give it more CPU power.

Treat yourself ;)

I reckon that should solve your problem, and get you up to a much more playable resolution. If I'm wrong, send it back as unwanted item within 7 days under distance selling act.

Nope, there is no dedicated cable that I can see!

I took out the extra gig before and it made absolutely no difference :(

Would it be possible to get a second PSU, run it outside of the case and have just the graphics card plugged into it?

But then i'd need another motherboard and i'm totally broke, i'm going to have to exhaust all other options before I can start forking money out - will check members market now even :)
 
You could do that, if you've got another PSU with a dedicated cable try just running the GFX from that. Then you could kind of rule out the PSU as a problem...

If you were getting another PSU capable of running the GPU then it would be better than the one you currently have, so why not just replace it all together ?

My lil bros rig is a AMD Athlon X2 3.1GHz (i think), 2x1GB DDR2, GTS250 and a 500W OCZ PSU and it deals with all the latest games well. Including Crysis.

Could you try overclocking that CPU ? see if that makes a difference.

No reason why you couldn't use a second PSU just for the graphics card to test, just make sure it has enough amps on the 12v rail.

How would I know that? :o

Because I have a spare PSU, not buying another one :)

I have overclocked it a bit, from 2.1 to 2.4 but there's not much difference really. Not a pro in overclocking so didn't want to push it too hard :)
 
That wattage psu is too low and the amps its kicking out on 12v rail are not going to be enough to power that card.

I reckon a good branded 550w will be ample providing it has a strong 12v rail.

Also you deffinately need a better cpu that 3200+will severly bottleneck your performance as it is trying to keep up with your gpu so the performance will be worse. However this will require a new motherboard as well.

Hope that helps buddy.
 
doubt its the psu tbh, looking at your spec i wouldnt expect crysis to run well at all. You say it was smooth before the upgrade? what in low settings maybe

Would you be able to spec one for me please mate? I don't have a clue what i'm looking for :p Ideally £50ish please!
