How to Improve Star Wars: The Old Republic’s Performance

So recently I recommended using Game Booster to improve your performance, but for those who do not want to run a third-party app just to be able to play, I found something else!

I read yesterday that a GM posted on the German Star Wars: The Old Republic community forums in reply to a person who had low frame rate issues. It was posted by “J3-H1” in German, now my German isn’t too great but thanks to my “Google Translate Fu” I was able to loosely translate it.

Basically J3-H1 is suggesting that the user having low FPS issues in Star Wars: The Old Republic should try to install DirectX 9.0c and report back if they had any luck with that.

DirectX 9.0 LogoSo the proposed theory is that Star Wars: The Old Republic wants to use DirectX 9 drivers, and people with later versions such as DirectX 10, DirectX 11 don’t have those particular drivers, which cause their installations to emulate/mimic these older drivers if they are missing them, thus resulting in poor performance.

Some people on reddit went from 5-10 fps to 25 fps in the hustle and bustle of the PVP battles on Ilum.

So, how do we go about testing this?

  1. Go to
  2. Download the file to install DirectX 9.0c.
  3. Once it’s downloaded, run the file and it will ask you to extract it to a folder. Extract it where you can later find and install it, as it comes with a setup executable.
    Pro-tip: Do not extract it straight out to your desktop you’ll end up with a lot of files everywhere, it does not make its own directory, you have to make one for the installation.
  4. Run DXSETUP.exe and let it install.
  5. Once installed, launch Star Wars: The Old Republic and see if it helped improve your frame rate.

The installation will handle itself, it won’t “downgrade” your current DirectX version, so if you have DirectX 11 installed and install the DirectX End-User Runtimes (June 2010), it’ll only install the files that you are missing.

Also, please note: You do not need to uninstall anything before installing the DirectX End-User Runtimes (June 2010).

According to the thread on reddit, some people are seeing huge increases on the Republic and Imperial fleets plus on Ilum, while some people aren’t seeing any improvements in their frame rate performance.

People trying this out but noticing no improvement in their frame rate might already have these files installed from other games and thus are running it already in a better shape they would have been without the drivers.

I will try this on my other machine later on to see if it helps the wife’s Star Wars: The Old Republic performance and report back later.

Reporting back: Turns out before I tried this I was averaging ~19-20 fps on my lesser machine, but after installing the drivers I went up to ~25 fps. Not a significant difference, but higher is definitely better than lower!

I noticed that when I record videos with Fraps I’m getting almost no lag, while before I used to have a huge lag spike every 50 seconds while recording.

Did you get any better performance?

It worked for me, did it work for you? Let me know in the comments!
