If you want to play the game in newer DirectX 12 , it could happen that after the loading splash screen appeared, it simply crashes. The solution can be found in PCGamingWiki:
- Go to
%LOCALAPPDATA%\MK11\- Open
UserSettings.ini- Find
RGBPeripherals = onandRGBKeyLighting = on- Set them to
RGBPeripherals = offandRGBKeyLighting = off- Save the file
Like with many other games, what worked under 25H2, stopped working in 26H2, time to have a look at the GOG releases of the Interstate series!
We start with Interstate 76 Nitro-Pack which is the easiest to get run, as the only issue here is the 3 fps throughout the whole game!
The only way to fix this is really, to disable G-Sync system wide in the Nvidia app before starting the game.
Even if I add the nitro.exe and set it up in Nvidia App to disable G-Sync, and frame rate to 162 (as I have a 165 Hz screen) and V-Sync on set to off or App driven, the game ignores that as the G-Sync indicator is displayed still as a watermark on the screen regardless.
Also forcing the game to use glide causes the error “unbound exception” and also using dgVoodoo2 as GOG Support suggested earlier simply makes the game ignoring those, I can verify that by neither the 3DFX (for Glide) or dgVoodooWatermark showing (for DirectX), seems DirectX5 games are especially complex.
Next up is Interstate 76:
Interstate 76 now shows the loading screen and instantly closes without any error message.
So I had a look and https://www.pcgamingwiki.com/wiki/Interstate_%2776 and ended up having success by applying the Crossgen116 Patch! (I did not install the optional add ons and mods that come with the patch, tho!)
Last but not least – Interstate 82!:
Unfortunately, like so many games since 26H2 , Interstate 82’s situation worsened with the latest Windows build.In fact the game no longer starts even. in task manager I can see it causes 16% CPU load and takes 0,8MB RAM, but apart from that i8stubz.exe just seems to be stuck there.
turns out there is a community patch on https://www.pcgamingwiki.com/wiki/Interstate_%2782 addressing all issues.
And it indeed works! As a bonus, it does support 1080p aka full HD resolutions now!
The game doesn’t support Full HD, 2K, 4K resolutions, which was never much of a problem for the Steam release as it had been updated with an earlier version of the widescreen patch. However under 26H6 this is no longer the case, and “full screen” only covers 3/4 of the screen!
The solution can be found in form of a newer version of the patch which adds Full HD, 2K and 4K widecreeen support. It is available for the disc release, the GOG and the Steam release alike!
I have taken this from my own guide that I shared with the project KQ8FixWin11 as at the time of writing this, what they offered, has an issue with camera control
Here is an updated list of the config of my system I tested this on since a few things changed since I participated there!:
Windows 11 Pro 26H2, Nvidia 5070Ti@16GB VRAM, 32 GB RAM, AMD Ryzen 5 8400F@4.20Ghz, Monitor: KOORUI GP01 2K @165, FreeSync Premium enabled in monitor, G-Sync enabled in Nvidia App, game ready driver 621.01 , Global Settings: 162 FPS, G-Sync enabled, V-Sync enabled (in contrast V-Sync disabled if available within game).
Here is what I have done to get it working 100%
Before 26H2, the game worked fine even without any patches, like the all-in-one patch, however since 26H2, an additional patch is needed.
So here comes my own guide to get it working properly:
Culpa Innata used to work fine in earlier builds of Windows 11, however on 26H2, the game starts with black sceeens, only sound can be heard.
As we have to fiddle with the game files anyway to make it fully work, why not also restoring the uncut content and add support for widescreen resolutions along the way.
We are referring to the Uncut Patch Guide on Steam:
The story of the mods and patches and DLCs for Split/Second on PC (Windows 11), Linux/Steam Deck is a complex and complicated one.
This post tries to reflect the reality of November 2026 and all its advantages and disadvantages and nuances.
It turns out, up until summer 2022, there used to be a “DLC by Elysium” mod, bringing all the extra content like cars and tracks from the XBOX version of the game to the PC Steam version. (also called “SplitSecondUltimate14551” or “Quarry track mod”) which ever since has been removed.
It ever since has been replaced by something called “Xenon”, which can be downloaded here.
According to my memory from the top of my mind, I did download a savegame file for the old DLC mod because there is a bug in the game that does not let you save your progress after season 1 so you will never have season 2 and further unlocked. I have had repeatedly tried.
Unfortunately the savegame collection available for download on the same page as the Xenon mod, will have all races unlocked and marked as won in 1st place, i.e. you cheated your way through the game. Not my style, hence I will rather stay with the old mod and the old savegames then having to re-do all my progress again from scratch.
Only minor disadvantage is, the gamepad is not working for navigation in the menu of the game, and for XInpuit you have to manually map each button first within the game.
Newly available for the stock game/the old DLC Mod and the new XENON DLC mod, is a 60 fps mod from October 2026 by ccollomb.
Also available is an online mod from November 2025 by Yellow, re-estsblishing online multiplayer for PC and SteamDeck (requires the Xenon DLC Mod to work)
If you are after the obsolete SplitSecondUltimate14551 DLC mod and/or its savegames, feel free to email me, I kept them stored.
I already wrote about disabling hi-res in the settings of the game to make it run.
New with 26H2 is, it won’t anymore start if more than 1 monitor is enabled in Windows 11 26H2, disable all secondary monitors makes it run again!
About Yesterday, I wrote in the same post how to patch a sound bug introduced with censorship done for the GOG and Steam releases. New for Windows 11 26H2 is the neccessatiy to use dgVoodoo2 or else it will hang at the first loading animation.
New is, that also now The Next BIG Thing requires the use of dgVoodoo2 or else it will hang at the first loading animation, too.
This game has the common issue of some bink videos freezing in full screen, since manually putting it to Window mode is not possible the only way is to ALT, CRTL and DEL it then return to the game and the rest of the splash screens past the first “Focus” one play without freeze.
Since the video files are packed, there is no easy workaround of the specific viedeo file causing the issue.
Hence, the easiest solution without going too much in your hair is using dgVoodoo2 again,
Just disabling the watermark and it successfully scales the native resolution of the game of 1280 x 720 to your Windows desktop’s one.
Since from now on, GSync works with my monitor, it is by default enabled, means in Nvidia’s APP, the global setting is 162 Hz which is just shy of the max refresh rate of 165, and VSync on while in the modern games themselves, vsync should be off.
Anyway, as reported earlier, e.g. in my System Shock Classic post, older DOSBOX 0.74 version which is the one mostly shipped with DOS games in Steam, only has a blinking cursor in full screen.
It’s usually a DOSBox fullscreen/renderer incompatibility with modern Windows, the NVIDIA driver, or a variable-refresh display.
The fix for this is changing in the config file
[sdl]
fullscreen=true
fulldouble=false
output=opengl
the output type is usually the culprit
output=opengl worked, however now it breaks off the intro at saying “Attention” at carmageddon max pack in dos box.
changing “core=dynamic” into core=normal fixes that.
