dmxdex2020 Posted March 2, 2013 Posted March 2, 2013 Using ipresentinterval causes my framerate to be lower and more irratic Turning it off sort that problem out however the tearing on fallout 3 isnt that good for my screen. I tried to use the normal nvidia vsync or the ingame vsync but it doesnt work. Any ideas?
prensa Posted March 4, 2013 Posted March 4, 2013 dmxdex2020 - Hello! Setting iPresentInterval=0 turns off Vsync in Fallout 3 which can gain some FPS but usually at the cost of tearing as you found. I leave on the game's Vsync but activate Triple Buffering in Catalyst Control Center as my card has good size memory, it makes up for the Vsync. I would imagine your Nvidia has a Triple Buffering option too. These settings are discussed in more detail here: http://www.tweakguides.com/Fallout3_5.html "Using ipresentinterval causes my framerate to be lower and more irratic" I note the irratic part there, do you mean your game sort of slows or speed up like a messed up film in places? That could be micro stutter, I get that with my quad core. I fixed it by using the excellent Stutter Remover: http://fallout3.nexusmods.com/mods/8886 I use the older FSR_4-0-7 version. You can tweak the .ini that comes with it to set the FPS to what suits you. You may need to try a few FPS variations before you get it just right or you may find the default works for you straight off. That smooths the game right out nicely & as I say I still use the games default Vsync. Hope this helps! Prensa
luthienanarion Posted March 5, 2013 Posted March 5, 2013 (edited) Setting iPresentInterval=0 turns off Vsync in Fallout 3 which can gain some FPS but usually at the cost of tearing as you found. This is a common mistake. While this is an option in other game engines to increase FPS at the expense of screen-tearing, it's a very bad idea with Gamebryo. The engine literally updates at your graphics framerate, which is why FPS should always be capped, and disabling v-sync causes other wierdness and timing issues.

dmxdex2020 Posted March 5, 2013 Author Posted March 5, 2013 Luth so what are you saying? Disable it and cap framerate?

prensa Posted March 5, 2013 Posted March 5, 2013 dmxdex2020 - Hello!"Why are you using the older version instead of the newer?"I've used the older version before the update came out without any problems & I've never been compelled to update. If it aint broke... etc. :)I've nothing against the update, it's just that I've never used it much whereas I've run with the 4.0.7 version for a long time & can thoroughly recommend that one.As to Vsync, as I said above, I leave it on to prevent the tearing & use Triple Buffering.The Stutter Remover fixes the micro stutter & runs the game smoothly.Prensa
