Just bought a ATI Radeon HD 4800 Video card a few months ago, and ever since im having fps drops.
for example counter strike 1.6, drops from 99fps to 20-25 every minute.
In COD5, fps drops drasticly and after it regains itself the cod speeds up for some reason and works 2 times
faster(run faster, shoot faster, reload faster).

OS:Windows 7, 64bit (same problem in XP as well.)
Processor:4 CPU 3.40GHz (2CPUs)~3.4GHz

trying to find the solution for a long time, and im not so good with computers.
and if i should put more system specs just tell me where to find them cuz i have no idea. :)

  1. Which 4800 card do you have?

    What cpu do you have?
  2. where do i check that?
  3. download gpu-z
  4. Download CPU-Z and GPU-Z.

    Or download SIW (system information for windows)
  5. CPU:

    Property Value
    Number of CPU(s) One Physical Processor / One Core / 2 Logical Processors / 64 bits
    CPU Full Name Intel(R) Pentium(R) 4 CPU 3.40GHz
    CPU Name Intel Pentium 4 650
    CPU Code Name Prescott
    Platform Name Socket 775 LGA
    Revision R0
    Technology 90 nm
    Instructions MMX, SSE, SSE2, SSE3, ET64, EST, HT
    Original Clock 3400 MHz
    Original System Clock 200 MHz
    Original Multiplier 17.0
    CPU Clock 3400 MHz
    System Clock 200.0 MHz
    FSB 800.0 MHz
    Core 0 Speed 2400.0 MHz
    Core 0 Multiplier 12.0
    L1 Data Cache 16 KBytes
    L1 Trace Cache 12 Kuops
    L2 Cache 2048 KBytes
  6. How much ram does this system have? Are there any other background tasks running? A p4 with hyper threading is decent enough for CS 1.6 but it looks like the system doesnt have much RAM which will bog it down quite a bit.
  7. Installed Memory (RAM): 1.00 GB
    And no retarded programs running in the background, NOD32, Soundmax, and Catalyst
  8. Anyone?
  9. 1. Use SIW or GPU-Z to tell us exactly what type of graphic card you have.
    The picture you have posted doesn't give us much details.

    2. Your CPU, the 90nm Pentium4, is a large bottleneck. Upgrade to a cheap dual core and you'll see noticeable difference. (although you might need a new motherboard since it might not be compatible). Core2s and PentiumDuals are great (stay away from the Pentium Ds)

    3. You will see improvement in more RAM, preferably at least 2GB total for XP or 32bit Vista, or 4GB for 64bit vista.

    And thanks for the other advices, really appreciate that.
  11. You'll have to use GPU-Z to find out if you have a 4830, 4850, or 4870. (based on the shader core, and DDR3 or DDR5)

    I'm guessing SIW can't provide in depth details about that.

    But anyways, the major bottleneck is your CPU. Check your motherboard specs to see if you can upgrade to a dual core.

    i dont really know how to tell if i can so here are my motherboard specs:

    Property Value
    Manufacturer ASUSTeK Computer INC.
    Model P5L-MX
    Version Rev x.xx
    Serial Number MB-1234567890

    North Bridge Intel i945P/PL/G/GZ Revision A2
    South Bridge Intel 82801GB (ICH7/R) Revision A2

    CPU Intel(R) Pentium(R) 4 CPU 3.40GHz
    Cpu Socket Socket 775 LGA

    System Slots 4 PCI

    Memory Summary
    Maximum Capacity 4096 MBytes
    Maximum Memory Module Size 1024 MBytes
    Memory Slots 2
    Error Correction None

    Yep, 640 shader cores. It's an ATI HD4830. It seems the core is 15Mhz OCed. (stock is 575/900)

    I have one for one of my PCs and it's a pretty good card.

    According to your motherboard info, I believe this is your motherboard:

    You might wanna double check.

    It says it supports 65nm Core2Duos/Dual Cores. You can find used 65nm pretty cheap nowadays - they usually go for under $100 on ebay.

    Core2Duo E6300 @ 2.13GHz

    Core2Duo E6600 @ 2.4GHz
    (ends in 20 minutes)

    Core2Duo E6700 @ 2.66GHz

    All of these Core2s can overclock quite nicely.
  14. thanks for your help ill go by myself from here.
