Here is a problem more people are hitting than you would think. NASCAR 26 runs fine and looks fantastic, but the moment you start a race your CPU pins at 100 percent, and suddenly the show you had on in the background stutters, Discord drops, and your stream buffers every few minutes. All you wanted to do was relax, put on some TV, and drive in circles. Instead the game is eating your whole computer.

The good news is that this is fixable, and the main fix costs you nothing you will actually notice. There is no hidden use less CPU slider, but there is something better, and most people in this spot are one setting away from a smooth, quiet race.

Why NASCAR 26 Hammers Your CPU

NASCAR 26 runs on Unreal Engine 5, and an uncapped Unreal Engine 5 game will use every scrap of processing power you give it. If nothing is telling the game to stop, it renders as many frames per second as it physically can, forever.

On a modern six or eight core chip you have cycles to spare, so you never notice. On an older four core processor near the minimum spec, something like an Intel Core i5-4430 or an AMD FX-6300, the game happily consumes the entire chip and leaves nothing for Windows, your browser, or anything else.

On top of that, a racing sim does a lot of its work on the CPU, not the graphics card. Every AI car on track is physics and logic the processor has to calculate. So a full field is a heavy CPU load before you even touch the graphics settings. That is the real reason there is no use less CPU option in the menu. The frame rate cap is that option, and so is the number of cars.

The Fixes, In Order

Do these top to bottom and stop as soon as your CPU calms down. For most people the first one is the whole fix.

1. Cap your frame rate to 60. This is by far the biggest lever, and on an oval it costs you nothing visually. Look for a frame rate limit in the game's video settings first. If there is not one you like, use the NVIDIA app or NVIDIA Control Panel Max Frame Rate under Manage 3D Settings, or AMD Chill and FRTC in the Radeon software, and set it for NASCAR 26 specifically. Turning on VSync does something similar. A 60 cap on a game that was quietly running at 140 hands a huge chunk of your processor straight back.
2. Cut the AI opponent count. Every AI car is CPU work, and it is usually a bigger cost than any graphics setting. If you are running full 40 car fields just to cruise around, drop the field to 15 or 20 and watch your usage fall. For relaxed laps you will not miss them.
3. Lower the settings that are secretly CPU bound. Crowd density, the number of visible cars and mirrors, and shadow detail lean on the processor far more than resolution or textures do. You said the game looks fantastic, so keep your textures and resolution and trim those three instead.
4. Update your graphics drivers and kill background overlays. Old drivers cause stutter on their own. While you are at it, turn off the Steam, Discord, and NVIDIA overlays and disable Windows fullscreen optimizations for the game, since those can all fight it for resources.
5. Let the first lap settle. Unreal Engine 5 compiles shaders the first time you run new content, which can cause a rough opening lap or two. That is normal and it smooths out, so do not judge performance until you are a few laps in.

The Wifi and Streaming Problem

Here is the part that confuses people. Your internet connection is almost certainly fine. What is happening is that at 100 percent CPU, Windows cannot give your network stack and your browser enough scheduling time, so streams stall and Discord drops even though the link itself never went down. Fix the CPU load and the wifi problem disappears with it.

Beyond the frame rate cap, two things help directly. Open Task Manager, find NASCAR 26 under Details, and set its priority to Normal instead of High so Windows stops letting it starve everything else.

And if you use a USB wifi adapter, move it to a different USB port, because a saturated processor makes USB polling hiccups much worse. Honestly, though, if the whole point is TV plus a race in the background, streaming the show on a phone or tablet sidesteps the entire issue.

Advanced: The engine.ini Tweak

If you want to squeeze out more, Unreal Engine 5 keeps a config file you can edit to strip out expensive effects the menus never expose. Back the file up first, because a typo here can stop the game loading.

Press Windows and R, type %localappdata%, and open the Maverick folder, then go to Saved, then Config, then Windows, and open engine.ini in Notepad. If you do not see a Maverick folder, look for the game's own folder in that same AppData Local location. Add a section like this at the bottom:

[SystemSettings]
r.AmbientOcclusionLevels=0
r.MotionBlurQuality=0
foliage.DensityScale=0.5

Those turn off ambient occlusion and motion blur and thin out background foliage, all of which buy back frames and processor headroom. Some flags may be ignored depending on the build, so change one thing at a time and test.

A Quick Low End Setup

If you just want the short version, set the game up like this and get on with your laps.

The Bottom Line

NASCAR 26 is not actually too much game for an older PC. It just does not put a leash on itself by default.

Cap the frame rate, trim the AI field and the few CPU heavy settings, and the game that was eating your whole computer turns into a calm background cruise that leaves plenty of room for your show. Cap the frames first. That alone fixes it for most people.

FAQ

Why is my CPU at 100 percent in NASCAR 26?

Because it runs on Unreal Engine 5 and, uncapped, it renders as many frames as your PC can produce while also calculating physics for every AI car. On an older four core chip that uses the whole processor. Capping your frame rate is the fix.

How do I cap the frame rate in NASCAR 26?

Use the in game frame rate limit if there is one, or set a per game cap of 60 in the NVIDIA app or Control Panel under Max Frame Rate, or in AMD's Radeon software with Chill or FRTC. VSync also works in a pinch.

Does lowering graphics settings reduce CPU usage?

Some do. Crowd density, visible cars, mirrors, and shadows are CPU heavy, so cutting those helps. Resolution and textures mostly load the graphics card, so you can keep those high.

Why does my wifi or Discord drop when I play NASCAR 26?

Your connection is probably fine. At 100 percent CPU, Windows cannot give your network and browser enough time to run, so streams stall. Cap the frame rate and set the game to Normal priority in Task Manager and it clears up.

Can a low end PC run NASCAR 26?

Yes. The minimum spec is roughly an Intel Core i5-4430 or AMD FX-6300 with 16 GB of RAM and a GTX 1060 or RX 570. Near that tier you will want the frame rate cap and the lighter settings above to keep it smooth.
