[Solved] GTA 4 and my 5870 no boost from 4870?

GTA4 is CPU intensive, but the framerate shouldn't dip on the improved GPU. Did you increase the settings? Are you benchmarking with the same settings?

soldier37 , the drivers are doing more work to drive this card than the 4870 . in that process , they eat up more cpu cycles , and less cpu is left for GTA4 . that said , gta4 is annoyingly dependent on cpu . in other games , you'll be pleased to own that 5870 baby !

How do you try to get off saying things like that ? "the drivers are doing more work..." Huh ? Do you have any kind of proof that the 58** series drivers rape the cpu to fully utilize the card ? I don't think so.... Clearly you are only speculating. The OP needs some intelligent suggestions to his problems such as : maybe there is a GTA4 bug with the 9.10 drivers, maybe he should try 9.9 and test again, or check to make sure that his clock speeds are being bumped up in 3d mode, or maybe he can fiddle with the catalyst a.i. settings and see if that helps, or just make sure that the settings are exactly the same from both benchmarks.

See, I came up with a few reasonable suggestions without trying to tell somebody that the 58** series drivers are bloated and need faster processors to cope than the 48** series...rediculous.

GTA IV needs to be overhauled or at least patched with a better engine that isn't so screwed up. It even makes the PS3 lag at times.

Well thanks for the input guys, i figured there was something up with gta 4. Going to install and check out Crysis warhead and far cry 2, flashpoint 2 and Borderlands today to see how they run. Proud owner of the new hotness here, might get a second one later for xfire.

Im hearing end of November Renz, seen some news on it yesterday... link below

thanks annisman for being moderate and not getting nazi over slight disagreements . yeah , even i'm interested for the OP to try 9.9 for this game , it no improvements then ill get a judgement over my speculation of the newer drivers/card combination eating more cpu .

all the games u've listed , yummy , far cry 2 is has wonderful open environment and a large , large map for you to explore !

To the guy that said the 5870 needs more horse power to run then the 4870. You said you are not speculating but YOU ARE SPECULATING. It doesn't take more horse power from the CPU (what you say was true in the single core days but not with a quad core) it just takes more CPU grunt to reach the video cards ceiling. You should not in ANY way see a performance drop on a quad core CPU. Think of it this way, The CPU takes this much time -------- (9) to render then image, then the GPU takes this much time -----(5), That means it takes -------------- (14) to render a complete image. If you cut off 2-- from the GPU rendering time then it takes ------------(12). So you can see even though the Video card is 2x as fast it might not seem a lot faster. In truth the GPU probably takes more time to render then the CPU. The CPU and GPU also render things at the same time ( they each render 3 frames ahead. Which sometimes causes mouse/input lag).

Its not a more powerful card that requires a more powerful CPU either, its the bulky drivers with a new generation of card that can cause that. While GTA4 is a CPU limited game, it is not bottle necked by the CPU. It is a nice balance. You wont see a linear increase from a faster CPU or GPU, it would take a combination of both.

Your premise for your conclusion is flawed because you are leaving out information, also what information you do provide shouldn't lead you to the conclusion you reach.

To the OP, Make sure VSynk is off as that can create an overall drop because without triple buffering your FPS has to be divisible to your Hz setting.
