cruisx Posted July 17, 2011 Share Posted July 17, 2011 Hey guys weird situation, for a 2500k and installed GTA IV this morning was running great with my HD 5830 @50-60fps on high settings. But when i went back to play it right now its not going over 30 and stutters a few times, usually starts around 20 fps. What could be the cause? I installed like 3 times same issue, any ideas?

Exxon Posted July 17, 2011 Share Posted July 17, 2011 Which patch do you use? Do you use commandline? Link to comment Share on other sites More sharing options...

What settings are you trying to run on? FPS fluctuations are not uncommon in GTA4 and it takes a while for some people to realise that it may have been 60fps at eg. the airport (near sea, fewer cars, etc), but 20fps in the middle of the city (much more demanding). Then, these people will post on here thinking they've lost overall performance when in fact their settings were too high in the first place.

basspower Posted July 17, 2011 Share Posted July 17, 2011 The processor is not the problem it could be the graphics card struggling or overheating. Mine seems to get laggy after an hour of play. I have the i5 750 btw. Link to comment Share on other sites More sharing options...
diablo440 Posted July 17, 2011 Share Posted July 17, 2011 It's a 1GB 128bit card, on top of being on top of ATI drivers, adjust settings. I use 128bit cards too but with 2GB VRAM, to save on power bill but still get good settings and frames. Link to comment Share on other sites More sharing options...
cruisx Posted July 17, 2011 Author Share Posted July 17, 2011 (edited) The problem is that its 20 all the time in every area, before it as around 56 at the start near the doc, outside the first save house it was 50-56fps, and in the city near the parks etc it dropped to 40-45. Im using 1.0.7.0 from steam i think thats what its called,its the latest one. settings were auto with 717/10XX used of video memory. ( all values high, water very high) vsync off. EDIT: Hmm just started the game again and seems to be fine now getting 45-55 fps all around with vsync on. Do you guys think it was a windows update issue? Last morning i shut the pc off while it was doing and update on shutdown and i didnt let it apply the updates when i started it back up.. This morning I turned it on and it applied all updates and seems to be fine. Edited July 17, 2011 by cruisx Link to comment Share on other sites More sharing options...
freak2121 Posted July 18, 2011 Share Posted July 18, 2011 Speedstep (if there is such a thing for i5 processors) could have been f*cking up and gone into 2D mode even when ingame. Link to comment Share on other sites More sharing options...
YankeesPwnMets Posted July 18, 2011 Share Posted July 18, 2011 Did you overclock the CPU or video card? Link to comment Share on other sites More sharing options...
BelowMe Posted July 24, 2011 Share Posted July 24, 2011 freak2121 Posted on Monday, Jul 18 2011, 02:52 Speedstep (if there is such a thing for i5 processors) could have been f*cking up and gone into 2D mode even when ingame i had simialr problem and went to bios and switched it off, didn't do the job so i switched off c01 or c10 or sth and the 2 options below it and it worked like a charm so like switch of 4 things speedstep n the other 3 options "C" options Link to comment Share on other sites More sharing options...

EIST (intel speedstep) lowers the multiplier and the voltage. As far as I know, the only difference between the two (aside from lowering vcore) is compatibility with certain operating systems. When EIST cannot be used, it will resort to C1E provided it is enabled in bios. EIST should be kept off when overclocking for stability unless on a Gigabyte board, in which case you can set your own dynamic vcore setting (took me alot of trial and error though, ugh!). C1E however works completely fine with overclocked processors as it doesn't seem to play with the voltages, only the multiplier. If you don't care about your power bill and temperatures at idle, you might as well keep them on. More info on the two in italics here C1E in depth: "Whenever the OS executes the halt instruction, the CPU enters what is known as the halt state. Architecturally, what's going on in a halt state is the clock signal is shut off to the CPU for some period of time. With no clock signal, none of the logic in the chip will do anything and thus power consumption is reduced. Performance is also significantly reduced; however, the halt instruction isn't usually called during application usage, so the performance aspects of the halt state aren't very important. The problem with the halt state is that it does nothing to reduce voltage, only current draw by stopping clocks from going to the CPU. Since Power varies linearly with both current and voltage (P = I * V), you're effectively only addressing half of the problem. The Enhanced Halt State, as Intel calls it, does two things: it reduces the clock speed of the CPU by decreasing the clock multiplier down to its minimum value (on the EE 965 series, that's 14x, or 2.8GHz), then reducing the voltage. The clock speed is reduced and then the voltage is dropped, to maintain stability. EIST in depth: "What EIST does is very similar to AMD's Cool'n'Quiet. It is demand based reduction in CPU clock speed and voltage. Using the same mechanism of adjusting clock speed and voltage, based on the application demand, the processor will dynamically increase/decrease its clock speed between its minimum clock and its normal operating frequency, as well as voltage, in order to optimize for power consumption. Because of the way EIST (and AMD's Cool'n'Quiet) works, there's inherently a drop in performance. The idea is this: if you're performing a task that's not using 100% of the CPU, the CPU will operate at a slightly reduced frequency in order to conserve power. So, while some tasks will require that the system run at full speed, others will run at lower speeds. " Link to comment Share on other sites More sharing options...
