Low FPS crysis 4870

Hello, I recently purchased a sapphire 4870 512 card and am only getting 10-25 fps @ 1440x900 with no aa or v sync. My system specs are:

Phenom 9500 @2.2GHZ
3GB DDR2 PC2-6400 240pin
720 GB (2 x 360) SATA 3G (3.0 Gb/sec)
600Watt PSU
ATI Saphhire 4870 512 MB


I see others saying they get 40+ fps with these kind of settings, Plz give your input

Try running it at high (DX9) settings rather then highest settings, the game is a killer. And yes you CPU is holding you back you might want to think about overclocking.

I am running Vista 32 bit, I can not over clock because its an HP motherboard.

I was thinking something is wrong somewhere because I was using a 9800 gt 1gb and only saw minimal increase in fps when getting this card.

If you jumped from a 9800GT to a 4870 and didn't see a performance gain, then your CPU is almost certainly a bottleneck. The PSU is also a possiblity though.

Its more about the rails than the watts. i like banging on about PSUs anyway, i think theyre hawt. gamerk316 is probably more accurate, theres no way id put a 4870 in with my 9500.

Link that 500w jobby anyway, lets have a look at it.

from memory i get around 32 with most settings on high at 1600 x 1200

nothing wonderful but most certainly playable

I have an hp...i am going to try using ntune tonight and see if that helps. my motherboard is an ecs mcp61pm-hm.

Its an Antec TP II

But honestly I don't think it is the power supply. Im getting same problems with far cry 2. Can someone please give me some more input

How do you think a phenom ii would fair me?

Found this on AMD's forums, this guys rig is very similar to mine.

Hey everyone I just made the switch over to ATI and bought a Sapphire 4870 512mb. I previously had an EVGA 8800 gt and was able to play FC2 on max settings @ 1440x900 with a very playable framerate. However, after installing my 4870 I get probably half the framerate with identical settings. Shouldn't the 4870 be able to eat this game for lunch? My specs are as follows.

Athlon x2 6000+ @ 3.0ghz

6gb ddr800

500gb WD HDD

550 wt Rosewill PSU

Sapphire HD4870 512mb


anymore input?

FC2 has alot of problems. It doesnt like most drivers and it hates ATI atm. Its not you its that super poor release of a game. I have already put mine away as it refuses to run decent on 2 machines.

Thank you, I am RMAing the card, sapphire said the cpu should be fine....but if the replacement does not work I'll probably get a phenom ii. I'll let you all know how it goes. Thanks for the advice.

When I said I updated, I at same time used the tlb fix for first time and pushed cpu to 2.4 on top of that. Frames jumped up quite a bit but not what I expected. I then tested without the cpu overclock, frames went back down to single digits. No matter what the resolution, things stayed the same.

I plan on getting a phenom ii this weekend and see how that goes. Hopefully this fixes all of my issues. If not I'm going to build an intel rig. Last chance AMD!!

Seriously though, this game just eats up PC resources like crazy. 25-45fps @ 1440x900 seems very reasonable for your setup.

At stock clocks, my setup is:

Q6600 2.4ghz
Vista 32
2x 1GB DDR2 667
650watt psu
VisionTek HD4870 (512mb)

And after updating my drivers and reinstalling the game, that's about exactly the same performance I got too.

The BEST thing you can do for that game is to go download the CCC 2.21 mod (with the ToD mod and realistic shadow option) and install it at Level 5, and run it in DX9. It looks BETTER than very high DX10 and I AVERAGE 37-38fps at 1440x900 with 8XAF and 0xAA at that point.

No joke, my average FPS went up a good 8-9 fps with that mod and it looks even better than Very High everything.

I have an i7 now. Never drops below 25 frames(even in intense fights) @ very high
