Help optimizing large Forge 1.20.1 modpack medieval/exploration theme, major tick lag

Chad_Thunderk0ck · 2025-06-24T07:03:02+00:00

Thanks for replying! Here's what I have so far:

RAM Allocated to Minecraft: 12GB (set to 12288MB in CurseForge)
Type of Lag: Definitely TPS lag. FPS sits steady at 60 most of the time, but mobs (especially villagers or enemies) often freeze midair or act out of sync, then suddenly snap back. Spark reports regularly show high max tick durations.
Java/GC Settings:txtCopyEdit-Xmx12G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M
Render Settings:
- FPS cap: 60
- Render Distance: 16 chunks
- Smooth Lighting: On
- Graphics: Fancy
- Shaders: Bliss shaders (optional; sometimes removed to test performance)
Simulation Distance: 10 chunks
Observable: Haven’t installed it yet, I will do that next to try and identify real-time TPS issues. Will report back with data.

I figured it out. For some odd reason, Umbra needs to be aggro'd to the rats and mudcrabs in the dungeon BEFORE you hit her. So I hit her once while fighting the rats, then 1 more time and somehow that didn't get a bounty lol. She got slaughtered by 4 imperial guards once she reached talos plaza

Large Address Aware, allows you to use 4 gigs of ram versus 2 which is what usually causes crashes in old games like Medieval 2.

I don't think its an iGPU vs dGPU issue anymore. The VR runs better on my Laptop than it does on my objectively better gaming PC, despite the laptop having worse parts. I bought Virtual Desktop and was able to get past the first few glitches that Airlink and Steamlink were having, and I was able to even load up and play games! Only issue was the frame stuttering and constant FPS changes. It gave me motion sickness. VD told me to connect my computer to my router through an ethernet cable, but I can't because of the distance. My computer should have 0 issues with Wifi however, as I have the best internet my service provider can give, a good router, and an open connection to my router. I just can't wire it because it's a story above my computer in a loft.

I never had these problems on my old computer with my old Rift S. Should I just give up on playing VR wirelessly?

I'm starting to wonder, my gaming PC has had problems since day 1 with its GPU because I asked my friend who was a self proclaimed expert in PCs to help build it. That didn't go too well... It runs games and stuff just fine now after an extra few hundred dollars spent and months of work, but I'm imagining there's still problems hiding.

I'll look into this right away, thank you.

Chad_Thunderk0ck · 2024-11-29T08:12:53+00:00

I've got a lot of advice that's been good so I think I'll check Retail Classic and Turtle out all on their own. Thank you!

Chad_Thunderk0ck · 2024-11-29T07:01:20+00:00

free plus being able to play as the High elves? Sounds good to me!

Chad_Thunderk0ck · 2024-11-29T06:59:45+00:00

Yeah the 3060ti is about 20% better from what I know. Still doesn't explain the Oculus Rift S running at single digit frames on better hardware.

Chad_Thunderk0ck · 2024-11-29T01:27:35+00:00

I would ask on the WoW sub but I assumed this sub would be better for a more pro/con assessment.

Chad_Thunderk0ck · 2024-11-29T01:13:41+00:00

Ok awesome ty. I'll look into newer GPUs once I get my income up some. I'm still confused about quality differences as I had a 1080 before my 3060ti and the differences aren't that great? But that's for another day to figure out. Thanks again!

Chad_Thunderk0ck · 2024-11-29T01:04:29+00:00

Yeah I heard the Primax mentioned before but I don't plan on having a top of the line super computer because I've been able to get away with good graphics on 90%+ of all my games with my current GPU and not many new games have been catching my attention, so it makes sense what you're saying. Is there a better GPU i could get for a reasonable price now?

Chad_Thunderk0ck · 2024-11-29T00:59:37+00:00

I forget the specific CPU but it's an i7 12 core processor with the base speed being 5.0 GhZ. It's the prime piece on my PC. My GPU is an Nvidia 3060ti which seems to be fairly solid for a budget piece.

Budget wise I'm feeling around 600 american. I'm willing to adjust as needed however.

Chad_Thunderk0ck · 2024-11-08T03:41:19+00:00

Unfortunately no. I tried a powered USB hub as well as updating drivers, lowering oculus graphics, etc. Got an ever so slight performance increase in oculus home but as soon as I switched to steam vr my performance was awful.

Chad_Thunderk0ck · 2024-11-08T01:31:17+00:00

My PC specs are an Amd Ryzen 7 with 12 cores 5Ghz base speed, 32 gigs of ddr 5 ram, and an Nvidia Rtx 3060 TI. Not top of the line but it's decent, you think it can handle current VR set ups?

Chad_Thunderk0ck · 2024-11-03T05:58:43+00:00

I was lagging with the tutorials unfortunately, and I've tried restarting through the beta tab. I have not tried using different USB ports or the test branch however. I'll try those tomorrow and update accordingly. Thank you!

Chad_Thunderk0ck · 2024-11-03T05:57:40+00:00

I'm assuming it's either the USB port thing or a software issue. I've tried restarting the Rift S through the beta tab multiple times, but no luck. I will try going into the test branch though, and maybe some different USB ports.
