Lag problem ( Directx 11 ? )

Recommended Posts

Hello everyone,


I just changed my computer for a new Acer Aspire AM3970-EB15P. It uses a ATI Radeon HD 7470 with 2gb Graphic card and it works under windows 7. However, after installing GTA IV and the last patch, the game is still lagging a lot. I don't know why, I bought that computer because it was better than my older one ( which was running GTA IV pretty fine but the computer died ) I was using a HP Pavillon but don't remember exactly the spec ...

I've placed directx 11 in the tittle because I found somewhere that it might not work with GTA IV, which is only compatible with Directx 9. I tried many things to put dx9 in my computer instead of dx11, or simply got both, but I was not able ...

Anyone can help me with that ? I don't know what I could possibly do, and I want to keep playing lcpdfr.

Thanks to every one for the future help,

Update your hard drive and GPU ASAP. Seriously, 5400 rpm HDD is beyond slow and the GPU is somewhat (is) a basement value card. A solid Raptor HDD, or SSD (maybe SAS HDD)... will net you better frame rates alone...

Thanks a lot for your anwsers guys. I'm going to check it out .. my cpu is brandnew, I can still change it for a better one at store so I'm going to take a look. Anyone has an Idea of the minimum Hard Drive speed needed for gta iv ? And I'm not really good into computers, what does GPU means ?

Again, a big thanks for both of you !

GPU (Graphics Processing Unit), aka your graphics card handles 95% of your systems graphic chores (pixel shaders, vertex processing, texturing, post processing, etc...). A good 7200 rpm WD or Seagate is good place to start with... If you have some money saved up, a good SSD would be even better.

allright. But that's weird ..my old harddrive was a way slower than my new one ( about 4000 rpm .. ) and was running gta pretty fine .. so I bet my problem is on my gpu ! 

 

Thank you again !
