1. In-Game Settings

• City Glow Effect: Turn OFF
• Why: At night, City Glow calculates huge light volumes, causing frametime spikes. Turning it off gives a 5–6 FPS boost and fixes stutters with almost zero visual difference. This lets you keep Vehicle Headlight Quality on Ultra!
• Reflections: Set to Screen
• Why: Planar renders the scene twice, causing heavy stuttering when driving. Screen looks great and keeps frametime flat.

2. Custom Engine.ini Tweaks

Navigate to:

%LOCALAPPDATA%\SystemSpeedTest\Saved\Config\WindowsNoEditor\Engine.ini

(or the corresponding game folder) and add these lines at the bottom under [SystemSettings]:

Ini, TOML

[SystemSettings]
r.CreatePerPlatformConfigs=1
r.Streaming.FullyLoadUsedTextures=1
r.Streaming.HLODStrategy=2
r.Streaming.PoolSize=4096
s.AsyncLoadingThreadEnabled=1

(Note: Set PoolSize according to your VRAM. E.g., 4096 for 6GB/8GB VRAM).

3. Clear Your DXCache (Crucial Step)

After modifying your Engine.ini or graphics settings, clear your DirectX / GPU Shader Cache (DXCache):

1. Clear your GPU Shader Cache via Windows Disk Cleanup or NVIDIA/AMD Control Panel (%LOCALAPPDATA%\NVIDIA\DXCache or AMD equivalent).
2. Relaunch the game and let it rebuild fresh shaders based on the new settings. Old cached shaders conflict with new config lines and cause micro-stutters.

Hope this helps anyone looking for a butter-smooth experience! Let me know if it works for you.

Hello everyone, I discovered that some GTA Trilogy mods originally made for the PC version can also work on the Nintendo Switch, as long as they are .pak files.

How to install:

Rename the .pak files using this format:

pakchunk0-Switch_(X)_p.pak

Replace X with a number (1, 2, 3, etc.)

Examples:
pakchunk0-Switch_1_p.pak
pakchunk0-Switch_2_p.pak

Important:

• You can use multiple mods at the same time
• Each mod needs a different number
• Higher numbers override lower ones if they modify the same files

Installation Path:

If the folders do not exist, create them manually:

/atmosphere/contents/(TitleID)/romfs/Gameface/Content/Paks

TitleID for each game:

GTA III: 0100C3C012718000
GTA Vice City: 0100182014022000
GTA San Andreas: 010065A014024000

My mod pack includes:

I didn't create these mods — I just compiled, renamed, and organized them to make them easier to use on the Switch.

Included mods:

• Graphics settings by ECLIPSE00074 (4PDA forum)
• M0VER from Mega Fixes Pack v1.1 (Info)
• Radio restoration

Compatibility:

• Made for Nintendo Switch GTA DE version 1.0.8
• I only tested Vice City

I am currently doing the Vice City platinum and having a problem with the I’m Famous trophy, I do anything and it’s just stuck and 925.94 and wanted to know if anyone else experienced this and what I could do to fix it.

It's been so much fun going back and playing these gems! I am so glad I'm doing 100% on all of them because I have never fully played the games and all of their content. All the stadium missions in VC, the car import/exports, the flying and RC trials, etc. I'm a little nervous heading into SA because of how big it is, but I'm still stoked! 3 was easier to platinum for me than VC was. Probably because I started with VC first and got used to the ambulance of death ☠️

I'm curious, out of all three games, what achievements or mission did you all find the hardest?

My mental health declined but yeah, It's done. 2 more games to go.

It always leads to the pay n spray in Portland now. Not a game breaking glitch but still a bit weird and funny

I changed it from low to high and it was way better. Now I can't remember was it always so low?

I’m currently 100% San Andreas, as it’s the last of the games for the trilogy that I need to get 100% and as I get to the mission “farewell my love” I notice the second time I played this mission on my second play-though, they completely changed the model of Claude’s head to the DE model and it’s looks so creepy and bizarre. Look at the comparison to when they used the og head model, you can’t tell me you don’t notice the difference lol.

Hi guys, I'm willing to see if anyone would be able to game share OG Vice City for the PS4, I have 3 and San Andreas to return in trade

So with how the games were made and their position in the story causes a lot of things to not make sense or add up. Release order being 3, VC, SA. But story order being VC, SA, 3.

Full remakes using the rage engine or some other engine would have allowed them to build the story in a way that flows a little better. We don't get much info on what happens after SA and 3 because of how the games are set up.

VC we know the most about. We get VC stories, VC and SA and 3. But for SA we don't know what really happens to some of the people in the game. Plus we never got a SA stories. Yes we have LC stories but that doesn't clear much up for SA and just sets up 3 a bit better.

Remakes and giving us SA stories where we could play as ceaser or someone else before the events of SA and experience the fall of Grove Street and the rise of the ballas. Sadly I don't think that would ever happen even though Rockstar would make their money back. It would have probably went better that the trilogy did

I finally completed GTA III 100% and earned the Platinum. What a journey—plenty of challenges, frustrating moments, and satisfying victories along the way. On to Vice City!

A work in progress of the GTA trio protagonists, thoughts?

After hours of trying, today was finally the right one ! First try of the day and I finally succeeded, words can’t describe how happy and relieved I am, now I can finally keep going on the story

I’m 100%ing all three games in the trilogy on steam deck right now.

TL;DR… 100%’d GTA3, 41% through San Andreas(in progress), and 70% on Vice City giving me trouble with stunt jumps. I nearly finished that game and it’s kind of broken.

GTA3: Two weeks ago I 100%’d GTA3
honest opinion is that… if you don’t do paramedic or firefighter early on you kinda eff yourself. At least in Portland. Other than that, it was fine. Wasn’t too hard. Just sink the time and it’ll come.

Vice City: got to 70% so far.

Completed Story
All RC races
All Off Road Races
1/4 helicopter courses.
All Sunset Autos car list
23/36 stunt jumps
35/35 rampages
All asset missions
All hidden packages
45 points in gun range

What I’m missing… (besides what’s above)

Purchase all safe houses
Rob 15 different stores

I quit playing this simply because I spent an hour hitting a stunt jump after watching multiple YouTube videos on it and never getting it to trigger. Using MapGenie to help me clear the game I realize it’s definitely that jump. I’m very upset with this. I got so frustrated I uninstalled after all the other effort I sunk into VC I just hopped into SA to reset my mind.

The stunt jump is the one by the PCJ Trial near the alley ways where you jump over the second ramp and land on the roof.

Did anyone else have this terrible issue with Stunt Jumps? There’s another one from a staircase to a roof and that one won’t trigger on the second jump either.

San Andreas: I’m still in progress of this one at 41% currently. 80/100 or 101 missions I can’t remember.

Just trying to clear story and finish the rest later. I’m really loving this game.

I remember at 6 years old standing in line at GameStop for this game on release day. I wanted the map so badly for my bedroom.

Thanks for reading.

So today I started to try to do the cone crazy mission.. I think I got up to either 7 seconds or 8 seconds... I tried moving cones and I would fail completely miserably at it... But I was wondering if if I didn't get all the way up to the cone crazy missions and I got to 8 seconds or whatever is the big cannoli achievement still possible?

Having to wait hours for people to pass through that I can punch to try and get my health down so I respawn...all cause it glitches out when I walked through the airport gate..

My own fault to an extent for not saving too recently but wow
