Richatu 1 Posted March 9, 2013 I used to run ArmA 3 at very crap framerates, but now I can play Wasteland with great fps and far rendering distances. This might not work for everyone but it's definitely worth a shot: 1. Go to C:/Users/''yourusername''/My Documents/Arma 3 Alpha and then open the Arma3Alpha.cfg file as a text document. 2. Find GPU_MaxFramesAhead and change it's values to 1; instead of 1000; or whatever it's at. 3. Now change the value of GPU_DetectedFramesAhead to 1; instead of 0;. 4. Launch ArmA 3 and drool at the framerates. Hope this helped you! (My specs: GTX 660 Ti 2GB, AMD FX 8350 8core 4.0 GHz, 16 GB RAM) Share this post Link to post Share on other sites
k3lt 3 Posted March 9, 2013 Using it for quite while, no fps improvement here. (found in another thread and forgot to change it back) Share this post Link to post Share on other sites
metalcraze 290 Posted March 9, 2013 GPU_DetectedFramesAhead is a value detected by the engine. Changing it doesn't affect anything. Share this post Link to post Share on other sites

Richatu 1 Posted March 9, 2013 placebo effect on mid-high end gpusi guess might change something on lower specs gpu´s. Would you consider a 660 Ti a low spec GPU? Im telling you the difference is incredible for me. You know the helicopter showcase? At the beginning where all the soldiers are running around near the choppers i had around 10 to 15 fps, and now i'm playing at 30+ at that scene. Also when playing wasteland i used to have an fps at around 25 with low rendering distance and no action. Now it's around 40 fps or more and i can have rendering distance at far.

St. Jimmy 272 Posted March 9, 2013 Oh those were already there. Will do this instantly because in Arma 2 it fixed my mouse lag. Share this post Link to post Share on other sites
Guest Posted March 9, 2013 Didn't we have to make the cfg read only in ArmA2 in order for the settings to not be overridden when the game starts? Try that. Share this post Link to post Share on other sites

(Sorry if i sound hostile, not my intention) im curious because the nvidia driver has a maximum pre rendered frames, its 4, the default in the driver is 2. this change afaik only affects the gpu behaviour and when on completely low settings fps doesnt change, it isnt the gpu bottlenecking the performance. my card is also a 660ti oc. even though i keep trying diff settings, the minimum fps remains exactly the same because its not limited by the gpu. but i digress, something did change, my fps was halved, used to be 18-22 on the heli on the ground and on top of the base everysingle time i tested and played, and now it became 9-13. limiting what the gpu renders had a negative impact. i locked the cfg file with read only so the game wouldnt override it when started. most settings are medium-high with some stuff turned off: http://i.imgur.com/BlD8XWs.jpg changing those settings never had an impact for me on arma 2 aswell, even on a different pc setup. and believe me, i tried everysingle thing there is. but who knows, maybe it worked for you, whats you processor and clock? can you post a screenshot with fps overlay on the same place i did?

Vooyek 1 Posted March 9, 2013 I have some increase in fps (~10) after i set GPU_MaxFramesAhead to 1. It bumped 1st cpu core usage (as this setting should) and in result it bumped gpu usage too. I have i5-3550 and HD7870. Share this post Link to post Share on other sites
chrisb 196 Posted March 9, 2013 I don't use it, but I have heard it can help. Don't forget though, as said above, mark the config to 'read only' or it will just reset everytime..:) Share this post Link to post Share on other sites

Okay so I tried out the heli mission again, this time with an fps counter. Turns out I'd gotten a bit too used to the mission being unplayable, and in fact I'm not getting these 30+ fps that I stated. At the location you took your picture i get about 25 - 30 fps at the same settings you have. At high/ultra settings i get around 20- 28 fps there. ( I also made sure to have around the same view distance as you have). Have you tried out multiplayer (wasteland, etc.) with these commands on? Share this post Link to post Share on other sites

Leon86 13 Posted April 22, 2013 The maxframesahead=1 thingy can help people that have a reasonably slow gpu. 1000 means driver default which is usually 3 (you can set it in the control panel). If you're gpu limited this means the cpu starts preparing the next frame, and when it's done the frame after, this means there's could be 2 extra frames between the mouse and the monitor, if you're only at 30 fps this will get you terrible mouselag (lots of time between user input and screen output) People with fast gpu's will be cpu limited anyway, so they'll never have the 3 frames buffer, or only have it when the fps is high. that's why they dont notice a difference. I've set my driver default to 1, I'd rather have good response than ~5% higher framerates. Share this post Link to post Share on other sites
