Fix Bad Performance after Installing iortcw

Iortcw brings many fixes to this game, such as better widescreen support, better lightning, openAL, while still faithful to original in gameplay. Unfortunately, after installing it, I always have such a bad performance..

Introduction

Return to Castle Wolfenstein is an old game, it was released in 2001. Because of that, there will always problems when we want to play it on modern system. Thankfully, there are many unofficial patch that fix these problems.

IORTCW

Iortcw is one of the unofficial patch or mod that brings many fixes to this game, such as better widescreen support. I only choose to install iortcw since this mod is still being faithful to original gameplay, and as my first experience playing this game, I want it to feel as vanilla as possible.

Installing iortcw

1. Download iortcw[github.com]
   Make sure you choose the correct version (I'm using "iortcw-1.51b-win-x64" since my windows is 64 bit)
   
2. Extract the zip file
   
3. Copy all the file from the iortcw folder to rtcw installed location
   
4. You can just delete the WolfSP.exe file, or rename it if you don't want to delete it
   
5. Rename ioWolfSP.x86_64.exe to WolfSP.exe (This is needed if you want to play the game directly from steam)
   
6. After this, whenever you run the game, it always using the exe patch file

Testing the Game and Fix the Problem

1. Try to run the game
   
2. You can go to option and change resolution, and video quality there
   
3. Try using the high quality preset
   
4. Now, try to play the campaign
   
5. I usually encounter performance issue especially after i walk the stairs, after the scientist and before the 2 soldiers, can be as low as 30 fps, and it will always happen all the time
   
6. Now, try to change the video quality setting, to low or medium (or normal, I forgot :P)
   
7. If you get consistent performance, you can try to change it back to high quality setting again, the performance should be fixed by now
   
8. That's it, no need to change "seta r_primitives" in wolfconfig.cfg

Something to remember

• Using iortcw gives you better widescreen support, and compared to unofficial patch by Knightmare, iortcw gives you better lightning
  
• I always get performance problem after installing iortcw, but this fix, which only changing graphic presets, really fix my performance, it's now constant 60 fps
  
• If you want to use vsync, just change seta r_swapInterval from 0 to 1 in wolfconfig.cfg on Documents\RTCW\main

iortcw is such crap, you change the resolution and it cuts off and breaks opening the options menu. to make it worse there is no fov slider in the options yet it is one of the major key elements it brings to rtcw. I'm just going to stick with vanilla rtcw.

Help! iortcw won't give me an fps of X anymore when setting com_maxfps!
iortcw now uses the select() system call to wait for the rendering of the next frame when com_maxfps was hit. This will improve your CPU load considerably in these cases. However, not all systems may support a granularity for its timing functions that is required to perform this waiting correctly. For instance, iortcw tells select() to wait 2 milliseconds, but really it can only wait for a multiple of 5ms, i.e. 5, 10, 15, 20... ms. In this case you can always revert back to the old behaviour by setting the cvar:

com_busyWait 1
