So, I have been getting some input lag in the game. I have been experimenting and I have found that 3 is the sweet spot for me... although I just suffered a CTD. Gonna mess with it more. The input lag was almost non-existent with the setting at 3. Read some good information on here: http://forums.electronicarts.co.uk/battlef...-extra-fps.html Credit is Muddr's for pointing it out to me.
Actually I had read the changelog, I just did not understand what it meant. It's possible that I still don't understand it.
If you have a quad core or above processor, with powerful GPUs, you may notice some stuttering issues with the latest update. This is because the new update made a change to how many frames your CPU calculates before your GPU renders. This for some can cause a bottleneck, stuttering, or even materials like smoke to look "scratchy". If your experiencing this set your 'RenderAheadLimit' as low as you can go until your game crashes.
There is another tweak. This one is within GameSettings.ini and relates to surround sound. Locate SoundSystemSize and set the value to 3 for X-Fi users and you should get surround sound afterwards. Set the value to 2 for other sound cards/processors for surround, may or may not work depending on your chipset.
So last night, I played BC2 with the best performance I have ever played with. I have kept Renderahead=3 and it seems to add the best performance/input. My system is still suffering a CTD every once in a while. I am getting an Application Hang on: bfbc2.exe The event ID is 1002 I have googled this shit and I cannot get any answers. This seems to be the same errors I used to get with COD4. I don't know.
