Step Three

To get the most out of this game, you need to open the control panel of your graphics card. I use a Nvidia GPU myself, so I can only make a walkthrough for this brand. I don't know anything about AMD Radeon GPUs, but I'm sure there'll something similar in terms of software.As a disclaimer, English isn't my native language so I don't know the exact designations, but I'll try to translate them as good as possible.At first, you need to open the "Nvidia control panel". There are multiple ways to access it, but sometimes the options aren't available for every user, so I'll list all ways which are known to me.1. Right click on the desktop background -> Open Nvidia control panel.Turns out that it can be that easy.2. If you have "Nvidia Geforce Experience" installed, click on the small upwards facing arrow in your right taskbar to show all hidden icons, right click on the icon of Nvidia and open the control panel.3. Can't access it on the desktop and don't want to download GFE? You may be able to find it in the "Windows control panel" (not the Windows settings). If you are using small/big icons, the Nvidia control panel is linked somewhere in this list. If you are using categories, you click on "Hardware and sound" and the link should be there then.It may take a few seconds to show up, but once the control panel opened you will see a few blue colored options on the left side. Click on "Manage 3D-Settings", now you can assign a number of graphic options globally or for single programs. In this window, click on "Program settings" (instead of the "Global settings") and select GTAIV.exe as the program you want to adjust. You may have to add it manually if it doesn't show up in the list.Now you need to adjust the following 3D-options:Antialiasing - FXAA =(ingame antialiasing makes things look too choppy)Antialiasing - Transparency =Power management mode =Texture filtering-quality =Threaded-optimization =Vertical Synchronization =Click on "Apply changes" on the lower right corner of the control panel to save the options.The adjusted settings will come into action on the next game start.
