Hello,

recently i've bought a gigabyte radeon 5770. i'm having some issues. most games specially recent games i play lags very much. for example if i play deus ex my fps stays most of the time at 20 and the game lags.

i have a g31-es2c mainboard, dual core e5400 2.6ghz, 450w psu, 4gb ddr2 ram. my monitor is a crt samsung 17" so i use a dvi adapter to use it. i have the latest update. so what is causing the problem?
 
At low resolutions like you are using that processor is definitely going to limit the HD5770. FYI Deus Ex has a bad issue with stuttering that has nothing to do with the hardware but you should be getting frame rates higher than that. You may be having driver issues. I would uninstall and use driver sweeper in safe mode to make sure everything is gone then reinstall fresh.
 
That mobo and and CPU combo will allow you a really great overclock
you will see a massive overclock maybe 1GHZ I have it at 3.4GHZ and could keep going with the same board and CPU. It's my media PC and Im using a low end cooler.

With my p45 board I made it to 4.16 but you could like I said maybe 1GZ
 


so do you think my crt monitor is causing this? current resolution is 1280x960 but i had to force set this with catalyst because it was always set to 1024x768.
 



i run mass effect 2 which gives 40-60 fps. but the problem is like when i'm running or turn the game lags. i had 4850 and i played mass effect 2 with max setting. it didn't lag before. so why now? i already used driver sweeper and reinstalled driver. no luck. so is it my monitor or cpu or gpu which is causing problem?
 
I am still sticking with my theory that your CRT (Which is probably heavier and bigger than your entire rig) is the one bottleneck. There is a emitter gun at the rear of the tube that "Paints" electrons in RGB very quickly but VERY SLOWLY compared to how fast a LCD can instantly have a pixel generate a color value virtually instantly anywhere on the monitor versus waiting for the CRT to make the pass to fill the screen line by line.
 

I don't know if you just made this up yourself or someone mislead you but the opposite of what you are saying is generally true so stop repeating it to others. CRTs usually have a higher refresh rate and response time than LCDs.
 
I have a radeon 5770 as well (not the same aftermarket manufacturer, but same card for all intents and purposes. First to clarify, you're not getting "lag".

Some things I would look at given the description of your problems, first make sure that in CCC/Ati Tray Tools you do not have frame buffer set to 1. This will generally cripple the performance of the 5770 on modern FPS's on a low-end system like yours (I also have an old dual core setup so I feel your pain). I prefer this set to 3, and in bad company 2 I used a frame buffer of 4 which actually made my highest overclock quit occasionally causing driver failure when scoping in and out quickly.

Another thing that you should look into is try ensuring that VSYNC is disabled. I say this only because in some cases, particularly with in-game set vsync, the vsync sets a standard divisor and if your frames drop below 60 (or 90/120 in your case with your CRT), it does not vary the divisor, leading to choppy gameplay and some excessively low fps (commonly in situations where you would have had 45-50 fps without vsync, the aforementioned glitch can drop you to the 25-30 range).

Look into overclocking your cpu and 5770 (and for this I recommend ATI Tray Tools since it does not have a top-end limit on the overclock slider, and the 5770 can surpass the upper-end 960mhz core clock that CCC tries to restrict it to). With my 5770 in most FPS online multiplayer I play at clocks usually 1010/1240, 1000/1300, 1010/1200. It depends on the game as to what clocks will remain stable on stock voltage. ATI Tray Tools also lets you set the voltage to constant max voltage allowed by the bios, instead of having the power-saving features enabled and this tends to make higher overclocks remain stable in games without having to flash to another bios.

This may sound dumb, but make sure all of your connections are tight and that your 5770 is in the correct lane on your motherboard. Check even the connection at the base of your monitor as well as the back of the computer.

In general, in Deus Ex Human Revolution, with my 5770 and dual core setup (and 4gigs of DDR2 ram at 800mhz lol 🙁 ), I'm able to maintain 50-60 fps fairly easily at 1680x1050. Make sure that you do not have things like anti-aliasing (AA, MSAA, etc) enabled as well. The only drivers that work well for a dual core cpu/5770 setup are 11.6, 11.6b, and 11.9. Make sure you are using one of these driver sets.

Your monitor being a CRT has nothing to do with low framerates as the above poster suggested and CRT's have for a long time been generally renowned as the preferred monitor type of some of the FPS-genre's elite players because of the resolutions they tend to come in, as well as their high refresh rate without causing image blurring (which generally occurs in most 120hz LCD's).
 


wow. thanks for the replies. 😱

as i already said i had to force my current resolution with CCC as my monitor does not set it do u think my card could be faulty? or the psu?
 



Sorry but I cannot give you a definitive answer on this question. I do not personally have an older CRT monitor (although I wish that I did). Make sure that you're in the correct resolution for your monitor's native res and make sure you're not playing windowed at all.

I could not tell you if your card is faulty or not, I don't have any experience with faulty 5770's. What is your PSU and how old is it? I suppose it's possible but you could check for how steady the voltage to your card is with a tool like GPU-Z.

gl, and sorry that you're having problems. I'm getting ready to upgrade now, but for a long time I've been on a dual-core/5770 system and it's like a mini-game trying to get the maximum performance out of it. However, when you do get your tweaks correct on a per-game basis, the 5770 really was a pretty incredible card and I've really admired how well it has aged given its price even at release. It is still a fine card for many games right up to the bf3 era =).
 


my monitor can handle resolution 1280x960 and when i had 4850 this resolution could be set with no problem but 5770 recommends i should have resolution 1024x768.

btw my psu is a fortrex 500w. sorry i wrote 450w by mistake. as far as i know my psu can handle this gpu but not sure. gpu temperature stays at 44 degree c when idle. when playing games it stays under 60.



thanks for the links. i will try to overclock.
 



about the resolution, after you first install the drivers you will have to manually set resolution so that is normal, don't sweat it. Your temps seem good and iirc 500w is spec for 5770 system (maybe 550w you might want to look into this).
 


yes i know its normal but what happened was when i set it to 1280x960 my screen looked like a wide screen with black border on upper and lower side of the screen. so i had to change the vertical and horizontal size of the screen with CCC and it took time to fix it in proper size. even sometimes it changes itself then i have to set the resolution again. 🙁

btw maybe it is dumb to ask but what do you mean by iirc?
