Radeon 5870 not fast enough

Hi there :)

Really disappointed with my Radeon 5870's performance in Crysis.

In Very High settings, I got 27 fps with my old card (GTX 260)
With the 5870 I get 30 fps, almost no improvement (was expecting at least 40)

There must be a bottleneck somewhere :(

I have a E6850 Core 2 Duo (3ghz) and 3 GB DDR2-800 Ram

I know that a quad core is really important for GTA 4, but according to this test: http://www.guru3d.com/article/cpu-scaling-in-games-with-quad-core-processors/9
it doesn't seem to matter that much in Crysis

I use win XP with the "Very High Settings" hack

Thanks :)

More about radeon 5870 fast enough
  1. Haha. You are in the same boat with me.
    I acted smarter and got 2x5850 and running them in crossfire.
    5870 gave me 32fps Now i got 45 with crossfire buddies
    at 1680x1050 resolution 4aa all enthusiast
  2. I want to add that 5850crossfire does about 55fps avarage on dx9 veryhight settings
    with 4aa. So this will really put a smile on your face!

    It's not the scaling it's the clockrate (although Crysis can use up to to 3 cores), since it's only a couple of frames faster I reckon you CPU is bottlenecking your card.

    Most reviews of the HD5870 show the HD5870 pulling about 40+ frame at v.high settings 1920x1200 no aa. And that article is very old there using a 8800 Ultra which gets bottlenecked at 1280x1024.
  4. I cry CPU bottleneck here.
  5. Your system isn't balanced, meaning that you have a high end GPU, and a low end CPU
  6. your system is very good ......and yur ATI is WOOOW,..................

    the answer 4 yur question is that crysis is based on Nvidia card ( and they are recomended 4 cysis)

    and it is also the same battlefield, batman and so on

    4 ati card : if you play resident evil or devil may cry....ati is at the top

    so some games works very well in some cards
  7. Well according to Toms review the HD5870 is capable of getting 35FPS at V.High no AA at 1920x1200 or 39FPS at 1680x1050 so take that as your basis.

    Also look in the review the GTX285 bumbles along at 25 and 30 FPS (depending on what resolution you play at) so with that in mind I think the OP is grossly overestimating the performance of his GTX260 or he's playing the game at different settings.

    There is no way a GTX260 is going to give you the same results as a HD5870, I suggest the OP installs his GTX260 again and plays Crysis at his monitors maximum resolution with all the settings at Very high no AA and runs a benchmark then comes back and posts the result, if the result is more then 24FPS at 1920 or more then 28FPS at 1680 then either Toms is telling fibs or OP is fibbing.

    Low end!!!

    That is not low end.

    1.8ghz single core would be low end.

    Take my system. With my system I get about 30-35fps v high 19 x 12 4xaa.

    However, if I were to reduce it to 10 x 7 it would jump to 60-70. Cpu bottleneck, nope.

    As the guys link shows, his cpu is capable of far more fps than what he is getting so the cpu bottleneck, is as always a myth.


    Yes low end in comparision to his GPU, he has a mid range C2D with a high end GPU. CPU bottlenecks are a myth eh? lol. ok. So your telling me if he were to play at 800x600 his CPU wouldnt be bottlenecking the performance of his GPU?

    His GPU is almost twice as powerful as his old GPU and he's getting just a couple more FPS. Maybe it is just an nVidia game, but i still believe its his CPU limiting the performance.
  9. would be very intesting to know if he was using different settings with his 260.

    I think 27FPS at those settings with a C2D and a 260 are possible considering he is using DX9. my previous rig had a c2d e8400 at 4ghz and a 4870 512mb and it could play crysis at 1920 x 1080 everything high no AA and get playable framerates.

    btw i do know what a bottleneck is. I had a pentium D with my 4870 before i got a c2d
  10. thats strange i have the same card and im getting around 42 to 46 fps avg on highest settings.

  12. It's a CPU-Bottleneck, Crysis's physics & AI are completely run by the CPU, try turning "Physics" in the Advanced tab lower, if you get more FPS it means a CPU-Bottleneck.

    Crysis can use 64-bit & Quad-Core CPU's, CryENGINE 2's affinity for nVidia is small.
  13. I went from a c2d 6600 OC'd @ 3.2ghz (25-30fps)

    Sound Blaster X-Fi Fatality


    To an i7 920 at stock settings. (33-40fps)

    I saw an increase of 8-10fps across all games. So a bottlenecking CPU is a possibility. I have first hand experience with it. Crysis takes advantage of quad cores also; albeit, not very well. I need a new gpu to take advantage of my cpu now.

    It has already been shown that it is not a bottleneck, it is not even a cpu limitation. It is a gpu limitation.

    Again, wait till the OP replies if he does to clear this up.


    How is it shown?
    CPU-Bottlenecks occur all over the place, you are placing a 1600 SP 5870 with a Core 2 Duo at a mere 3GHz, the C2D's got what, less than a quarter of the 5870's transistors?

    Do you know how much AI & Physics calculations are happening at very high? The shadows, time of day, AI, physics, all of that is CPU-driven.
    AI is incredibly intensive, for example, the game C&C 3, not very intensive. I had a C2D at 2.2GHz, and a 4670. At ultra high settings, everything is smooth until I put 8 Brutal AI's.

    GTX 260 - 27 FPS
    5870 - 30 FPS

    How the crap is that NOT a cpu-bottleneck?
    If you had a Q9550 it would jump easily to 40 FPS.

    Let me tell you something, there's Phenom II's, i5's, i7's, yes a old 65nm C2D would be considered Low-End now, especially paired up with a monster GPU like the 5870.
    OP, turn the resolution down, if FPS doesn't jump higher then it's a CPU-neck.

    That's with 4xAA.


    Using the BenchmarkGPU, I get 16FPS on Very High with a 4670, the 5870's more than 4 times the power of the 4670.
    OP needs to try the BenchmarkGPU & BenchmarkCPU in the Bin32 folder.
  16. Even if there isnt a CPU bottleneck a more powerful CPU will increase performance because as sabot00 has stated Crysis is very CPU intensive.

    Would be interesting to know the resolution the OP tested at.
  17. Been wondering that.
    Even at 1920x1200 without AA a 5870 (with no CPU-neck) should probably get around 40 FPS.
  18. I don't think the OP will reply. Maybe we have answered his question.
  19. I guess we should let it die until OP digs it out again.
  20. @TOPIC CREATOR

    Since you went from Nvidia to ATI, you need to make sure all the drivers are proiperly uninstalled.

    First use the program's default uninstall to get rid of the files.
    Then download drive-sweeper and get rid of the hidden NV drivers in your registry.
    (also run it in safemode to be sure)
    Finally, redownload the latest ATI drivers

    Yes and? None here knows what settings the OP is using, so no point arguing about that.
  22. The physics system on crysis will bottleneck the fastest cpu on the market . Even an i7 will hit a cpu bottleneck in crysis during an intense firefight . There are no limits to the amount of physics calculations you can force on your cpu with crysis . You can always blow up more buildings at the same time thus you can easily bottleneck your cpu . The physics scheduling system on crysis is incredibly poor . You can maintain a higher framerate in crysis during the 2nd cpu benchmark by using the console to change the thread used for calculating physics during the benchmark . everytime framerate drops type 'sys_physics_CPU='?(+/-1)' and the framerate will come to life again (until it bottlenecks and then you can swap it back to the core you were just using . If crysis was 'quad aware' , then it would do that job automatically and then there wouldn't be as much of a bottleneck .
    But it's not , thus I doubt there will ever be a cpu fast enough to run crysis under all prossible gaming conditions . That said , you can have a great gaming experience with an i7 or maybe a phenom II BE , but an old core duo isn't gonna help you at all .

    Crysis has both a gpu and a cpu bottleneck with the most powerful hardware available . It's symbiotically demanding . Sometimes it needs more cpu power , sometimes more gpu power . The best thing you can do to play it at v-high is just get the fastest PC possible & overclock it (And even then it will only take a bit of mass physics to bring it to it's knees) .
