Help with FPSPlus

[VerdExNeon]

So, I'm on a pretty bad laptop trying to play on my modpack, but I'm getting alot of lag and low fps. I've heard of the fpsplus mod that'll increase my fps alot, but in order to add it I need to put "-Dfml.ignoreInvalidMinecraftCertificates=true -Dfml.ignorePatchDiscrepancies=true in the start up parameters for it to actually work. I havent been able to find a way to get to the start up parameters in the technic launcher and am looking for help in getting it on. I've seen other modpacks that have fpsplus installed an example found here: http://www.technicpack.net/modpack/details/captain-sparklez-ultra-modpack.266188

Note: I've tried using optifine, but it doesnt agree with some of my other mods and causes me to crash frequently, leading me to another alternative.

Your help is appreciated.

 

Also if you have any other suggestions to decrease lag i would also appreciate that.

• Try OptiFine and fiddle with the settings. Sometimes it helps, sometimes it doesn't.
• You can add startup parameters by editing the version.json file in your modpack.jar.

Okay this may be a dumb question, but where exactly should I add this? I;m mainly just scared that I'll mess it up and break everything. (Already did that yesterday...)

If you open the version.json file from the modpack.jar in a code based text editor (i.e. Notepad++, Vim, etc.) you can see some existing parameters listed. Just add yours.

So I'm playing through The Serendipty Unlimeted and i'm trying to install optifine and i have deleted all the meta-inf's and it starts up fine but when i load my world it crashs and sends me back to the Technic Launcher and i've looked around on the forums and on the mod pack forums and didn't find enything that helped

[plowmanplow]

In the Forge/MC 1.6.4+ versions of OptiFine you simply drop the JAR file in your mods folder.

Yah I know that but his is 1.7.10 and every time i drop the .JAR in it crashs my game not when it loads up but when i try to load my world and then when i take it out it works fine

[plowmanplow]

@Daniscool: That's because OptiFine does "weird sketchy things" and is often incompatible with a ton of mods. Make sure you are using the latest version for your version of Forge/MC. If that doesn't work you won't be able to use it.
