pacwarz Posted November 11, 2008 Share Posted November 11, 2008 I have a Q6600 2.4 quad CPU, 4GB of RAM and a ATI HD 4870 on Vista 32 bit. Video card overclocked to max in catalyst control panal. Running San Andreas on Highest settings, 3x antialiasing in 1440x900. Those specs should murder the game, but i get lag. If i do a wheelspin, my fps drops to 28/30 and sometimes just driving round LV gives me random lag spikes. I also have latest drivers as of 15th october. it makes no sense!

Knyte Posted November 12, 2008 Share Posted November 12, 2008 Are you having constant "stutter", or just ocassional lag? Have you tried changing the CPU affinity to a single core? (While in the game, alt-tab out. Press CTRL-SHIFT-ESC to bring up the Task Manager, Click on the Processes Tab, then right click on the process for GTA:SA. "GTA-SA.exe" IIRC. Click on "Set Affinity", and then uncheck all but one box.) See if that helps. Otherwise, it may be a problem with your video drivers, and/or the Radeon doesn't like doing the particle affects. (Since you mentioned the drop when smoking the tires.) Link to comment Share on other sites More sharing options...
pacwarz Posted November 12, 2008 Author Share Posted November 12, 2008 I've tried playing around with affinity, it was already one one core just now, and i tried with all 4, and many combinations but it makes no difference. The lag isnt stutter, its just random spikes when i drive around, and of course the smoke. Im pretty stuck for ideas lol, it ran better on my old 7900GTX. Thanks for the reply though Link to comment Share on other sites More sharing options...
Spider-Vice Posted November 12, 2008 Share Posted November 12, 2008 I can run my game at max in a nVidia 8500GT, you should know that ATi wasn't ever "too" famous.

pacwarz Posted November 12, 2008 Author Share Posted November 12, 2008 yea alright, i guess that GTA is just very badly optimized for ATI ! that sux pretty bad lol. Link to comment Share on other sites More sharing options...
Starion Posted November 12, 2008 Share Posted November 12, 2008 San Andreas is badly optimized full stop. It gets lag spikes sometimes even with a 9800GTX. Though it is optimised better for Nvidia. mod it with Nitrous Oxide and chassis dyno. Link to comment Share on other sites More sharing options...
lscratcher Posted November 13, 2008 Share Posted November 13, 2008 or maybe its the fact that gta san andreas is not compatible with vista i had a few problems playing on vsta and i have low fps with my hd2600xt , 2,4 gh celeron and 2 gb ram try it on xp and ull see Link to comment Share on other sites More sharing options...

You need to deactivate the frame limiter. w/o that the game start to run at 60Fps. Link to comment Share on other sites More sharing options...
