Iron Man on PC never got patched on Steam, it only ever got updated for the retail release. This will update your game to the latest 1.1 patch of the game fixing game bugs. This will also provide you a way to change your game resolution to higher than 1680x1050 and run at higher than 30 FPS.

Installation

It's very simple, I've extracted all the changed files from the retail release patch and packaged it into a simple zip file that you will only need to drag and drop into your games folder.

Download the Iron Man 1.1 Patch[drive.google.com] and unzip the files into your install directory.

Change Log

• Keyboard Configuration – There are certain keys/buttons that do not properly clear the existing function when a new function is assigned, when configuring the keyboard and mouse controls. Left handed players in particular will want to apply the patch for this reason.
  PLEASE NOTE:
  If you already have a saved game, your keyboard configuration is saved with the save game. After applying the patch, in order to properly configure your controls, you will need to load your saved game first, and then configure the controls in the options menu. (If you configure your controls first and load a saved game afterwards, the old control settings that were saved with your game will be loaded.)
  
• Gamepads – Increased the number of PC gamepads that are supported.
  
• Performance – Increased performance and frame rate on certain missions.
  
• The patch includes a number of smaller bug fixes.

To change your resolution and your FPS limit, just open up the engine.ini file. Inside change these lines.

MaxFPS = 60
PCViewerWidth = 1920
PCViewerHeight = 1080

You can change these to whatever you want, just update them to your resolution and desired refresh rate. You will need to also set the engine.ini file to read-only or the launcher will override these changes at each launch.
