Ok, so I have been looking everywhere all over the place for solutions on how to fix these rendering issues to where graphics on buildings and roads do not load properly. Sometimes they did not load at all. An example was the mission where you have to choose between Playboy X or Dwayne(I did X and no I won't spoil what exactly happens in this mission) and then after he jumps across the roof you need to take the staircase down and when you do, the walls were invisible from the inside.
Right now I'm at the mission to where you have to track down a helicopter and take it to an airport, the one called "Dust Off". When I take off with it, the city isn't showing properly and it takes just a second to load but the real bad part is after you land it in the spot it needs to be and then the loading time takes forever to where I cannot get past it. Tried uninstalling the game and reinstalled it, didn't work. My game isn't modded either.
First I'll show you my specs.
8.00 GB RAM
AMD Phenom X4 965 Processor 3.40 GHz
ATI Radeon HD 5800 Series(specifically 5830)
I rightclick my desktop and choose advance settings to show my graphic card memory. I hear that commandline goes by "dedicated video memory", which mine is 1024 MB.
Here is my commandline:
-availablevidmem 1024(and yes, I've tried changing this value to many different numbers)
Video mode: 1920x1080(60 HZ)
Texture Quality: High
Shadow Quality: High
Reflection Resolution: High
Water Quality: High
Texture Filter: Tri Linear
Night Shadows: Off
View Distance: 55
Detail Distance: 50
Version of GTAIV: 18.104.22.168
So, what shall I make my availablevidmem be and what else needs to go into the commandline? I know commandline fixes a lot but it all depends on the computer specs and what commands are thrown into the commandline. And yes I do run LaunchterGTAIV.exe as administrator.
