Hello, I've recently launched a private modded server for myself and a few friends to play on. I've got quite a bit of experience running heavily modded servers for friends, but this is my first foray into 1.10, and one friend is experiencing extremely low FPS; about 2-4 frames in game, which is obviously unplayable. Meanwhile, myself and two others can play at a near constant 60 fps with vsync. It seems improbably that, with his specs, we would see such a huge difference in performance, so I'm wondering if the issue may be that he's on an AMD card, which have been known to have issues with minecraft and/openGL in recent years. If so, I'm hoping there's a fix.
We are in fact playing on a HEAVILY modded server. Forge shows 352 mods loaded, which I know is on the very extreme end of things, but it's very much playable on my end, and with the machines we're all running, there shouldn't be such a massive difference in performance.
My system:
Intel Core i7-4790k @ 4.0 GHz
16.0 GB DDR3 RAM
Nvidia GeForce GTX 970
In-game 60 fps with vsync.
Friend's system:
Intel Core i3-4360 @ 3.70GHz
16.0 GB DDR3 RAM
AMD Radeon RX 470
In-game 2-4 fps with all settings minimum.
It seems likely to me that perhaps the GPU is not properly kicking in for minecraft, in this case. That's kind of a shot in the dark, but I've heard of similar issues. It seems unlikely that him running a same-gen i3 (as opposed to i7) would be the issue, since Minecraft hardly utilizes multiple cores anyway. It also shows his CPU and GPU utilization are extremely low when he runs the game, so something is up. We've checked that he's running 64 bit Java. We've checked his memory allocation. All are what they should be. We've also tried both with an without Optifine and BetterFPS to no avail, so I'm at a loss. He should definitely be able to get a playable 30 fps at the very least, on a system that has and can run Witcher 3 at max settings, 1920x1080 at 60fps.
A few notes:
We're running forge 1.10.2-12.18.3.2281
We're using MultiMC to run the mod pack, if that's important.
I'd post his latest fml client log, but there's no indication of anything hampering performance from what I can see. The file is 11 MB as well, so it's a pain. I can post it if need be.
I know full well we have more mods than would usually be considered reasonable. If it really is just that his system is running to its fullest potential and that we need to slim down, then I'll do so. I suspect that's not the case.
I've scoured the internet for similar issues, and only seen a few posts on various other forums, all unsolved. Additionally, I've seen "benchmark" type videos of people running the same hardware getting hundreds of frames with shaders, etc. I'm at a bit of a loss what his machine might be doing. I'm just hoping there's someone out there who's solved a similar issue before that might point us in the right direction. Thanks in advance!
When he presses F3, what is shown in display adapter?
It shows his GPU, as it should. The program GPU-Z is also showing 80-90% GPU usage while mc is running, so it's likely not the GPU issue I thought it was.
I've noticed he's allocated 12GB ram to Minecraft, but Minecraft/java refuses to use more than ~4.5 GB of it, no matter what. His f3 screen is showing Mem: 38% 4180/10923MB, with still a constant 2 fps, and 0 chunk updates in singleplayer. This definitely tells me his ram is bottlenecking, but I have no idea why. His windows resource monitor is also showing the proper allocation, with plenty to spare for system processes, etc.
Before anyone cries out: "DON'T allocate that much to Minecraft! It just bogs down your system!" In this case, with this many mods, it's necessary. And like I said, myself and others can run this setup without an issue, with the same ram in our machines.
Is there anything known to prevent minecraft/java from using the full amount of ram it's been allotted?
Allocating more RAM makes it worse, dont give more than the default 1G unless you need it(and try with 2GB and 4GB), and you dont need more than 4GB even with that amount of mods
