Proper FOV patch.

[Miner Of Worlds]

I figured out how to patch the FOV so you don't need to use the aspect ratio workaround anymore. This requires the resolution fix.

• Open OFDR.exe in a hex editor.
  
  
• At offset 0xDAA330, replace d90534273901dc0d182d3301d91dbcde4f01c3 with c705bcde4f0100006c429090909090909090c3.

This will change your FOV to 59 vertical (around 90 horizontal with a 16:9 aspect ratio).

To change it to whatever you want, do this:

• At offset 0xDAA336, change 00006C42 (hex for 59 as a float) to the vertical field of view that you want.

THANK YOU

Hey, I want to make a similar fix for Ghost Recon Advanced Warfighter, any chance you could give me advice in finding the base address using cheat engine so that i can permanently edit the value in hxD?

Have you found where the FOV is in Cheat Engine?

I was able to make a Cheat Engine script to change the FOV in GRAW 1, but I'm not sure how you could make it into a normal patch.

That's great thank you. What would be the hex code for 43 vert / 70 horizontal FOV? Thanks

00002C42. Most hex editors have a sidebar that lets you input the float value you want.

Thanks for that. Will give it a try.

what a difference the FOV makes!

Wow this new FOV is great! Just wondering though, is it possible to hex edit the LOD values or how long the bodies stay on the map? Think that's the only issue I have now with the game.
