Hello, on GTA 4 and TDU2 i get wierd preformance, it looks like some frames are being skiped. In GTA4 when you drive it looks like you getting teleported foward, very disturbing whne turning, and in TDU2 i get same efect only if i reduce grafics to medium on tdu2 frame skipping is gone and i have stedy 60fps but if I go to high i get 40-50fps and the frame skipping is very noticable. So question is can i fix it somehow or is it poor game coding? And whould system upgrade would help? I got Phenom II 1055T at stock and AMD 5770 at stock, 8GB DDR3 1333MHz, seagate 500GB sata 3 HDD, I play on 1080p.
PS, in no other games I get frame skipping.
It means your system isn't capable of rendering the frames at the settings or with your resolution. Another possibility is that you're experiencing screen tearing which can be fixed by enabling vsync but only if your system can run the game above the display's refresh rate at all times during gameplay or it will not work.
As mentioned, I'd enable VSYNC and see if it resolves the issue, if it does, what you're seeing is tearing, which is normal when you have VSYNC disabled.
Yeah it might be screen tearing but the disadvantage of having the v-sync on from the game settings is it will drastically reduce your frame rate in some games. The solution is to make your graphics driver force the v-sync on, it can be done on both nvidia and amd.
Nah its not vsync, i got 35-44 fps on high, and 60Hz monitor
GTA4 is a very poorly optimized port from the consoles. AMD 1055T is around or under the i5 and i7 for performance, but normally more than enough. The weakness might be the video card or the drivers. You could add another 5770 for Crossfire and improve the performance or upgrade to a better video card. But before that have you patched or updated the game yet?
I have it on steam its automaticly updated, and latest video drivers, the thing is that its very smooth, i just get that frame skipping every few seconds, very annoying
Hard to say what is causing your problem with this game. But I can say you are not alone with these issues and GTA4 on the PC.
GTA IV is a very CPU taxing game. If you're got a strong quad core and plenty of RAM, the game should run relatively smoothly. I've got an i7 920 at stock with a GTX 295 and I can max the game out at 1920x1200. It may be that the game favours NVIDIA cards or something so AMD owners may have issues with optimizing settings within the game.
Hey I found something, theres an option on GTA 4 near resolution 1920x1080 @ 30Hz, Im thinking that mabey if game would limit my FPS that my VGA can eazily achieve it would stop frame skipping, like TDU 2 stops skipping frames after FPS reaches 60, but when i set it to 1920x1080 @ 30Hz on GTA4 my monitor says mode not supported. So mabey someone knows can i make my game limit FPS like vsync but not to 60 but 30~40?
I finaly solved this problem. :D
So if someone has frame skipping (some people call it stutter) in some games, like i do in GTA4 and TDU2 all you need to do is to look what average FPS do you get in game, then download program called "Dxtory" free trail version will do just fine, in that program click on "Advanced" there will be a microchip icon, then at bottom of list you will see "Limit video FPS" check it and set the value of average FPS that you get in game.
This helep me, you might find command lines for some games that limit FPS, but diferent game engines usualy use diferent commands so this is convenient program.
PS. this is video recording program so you will see your FPS at corner to disable click on "Overlay" tab and uncheck all of it, and if game gets chopy with limited FPS try disabling Vsync in game.
