If _summer is running on your integrated graphics instead of the dedicated GPU, you may notice low FPS, stuttering, slow texture loading, or crashes. High CPU usage can make the problem worse, especially when other applications are running in the background.
The good news is that you can usually fix the problem without reinstalling the game. Try the solutions below in order.
The most common causes include:
If your PC has both integrated and dedicated graphics, Windows may assign the game to the wrong GPU.
If _summer isn’t listed, use Browse to add its executable file manually.
Open NVIDIA Control Panel > Manage 3D settings > Program Settings.
Select _summer, then set the preferred graphics processor to the high-performance NVIDIA processor. Apply the change and restart your PC.
Open AMD Software: Adrenalin Edition and add _summer to your gaming profile. Make sure the game is configured to use the dedicated Radeon GPU rather than integrated graphics.
A faulty or outdated driver can prevent games from properly using the dedicated GPU.
For the best results, you can also install the latest driver directly from your GPU manufacturer’s official software or website.
If the problem started immediately after a driver update, rolling back to the previous stable driver can also help.
A game can reach very high CPU usage when other programs are competing for system resources.
Press Ctrl + Shift + Esc to open Task Manager. Under Processes, check which applications are consuming significant CPU, memory, or GPU resources.
Close applications you don’t need while gaming, particularly heavy browsers, launchers, recording software, and other demanding programs.
Don’t end Windows system processes unless you know what they do.
If the game is still stuttering or crashing, temporarily reduce its workload.
Open _summer’s graphics settings and try:
Restart _summer after changing the settings.
If the game becomes stable, gradually increase the settings until you find a good balance between visual quality and performance.
Seeing 100% CPU usage doesn’t automatically mean the CPU is faulty. A demanding game can legitimately use nearly all available CPU resources.
The important thing is what happens alongside the 100% usage.
Open Task Manager > Performance > CPU while _summer is running and check whether:
If another application is causing the CPU spike, close it before launching _summer again.
If you’re playing _summer through Steam, corrupted or missing files can cause crashes and performance problems.
Steam will replace files that are missing or corrupted.
A simple restart can clear temporary resource problems and background processes.
Before launching _summer again:
Then test the game again.
If none of the above solutions work, reinstalling the game may help, particularly if its installation is badly corrupted.
Before doing this, verify the game files first. A complete reinstall can take considerable time and may not fix a problem caused by drivers, Windows, overheating, or hardware limitations.
If Task Manager shows the dedicated GPU at very low usage while the integrated GPU is doing most of the work, check the Windows Graphics settings again and make sure the monitor is connected correctly.
On desktop PCs with a dedicated graphics card, the display cable should normally be connected to the graphics card’s video output, not the motherboard’s display port.
Also check your GPU temperature, CPU temperature, available RAM, and VRAM while playing. These values can help identify whether the problem is actually GPU selection or another performance bottleneck.
Windows may have assigned the game to integrated graphics, or the game’s workload may be more CPU-heavy than expected. Set _summer to High performance under Windows Graphics settings and check GPU activity again.
Not necessarily. High CPU usage can be normal in demanding games. It becomes a concern when it is accompanied by overheating, severe stuttering, freezes, or repeated crashes.
Go to Windows Settings > System > Display > Graphics, select the game, choose Options, select High performance, and save the setting.
Yes. Driver problems can cause crashes, graphical glitches, poor GPU utilization, and unstable performance. Updating or clean-installing the appropriate driver can resolve these issues.
Only after trying simpler fixes such as updating drivers, closing background applications, lowering graphics settings, and verifying the game files.
_summer not using the dedicated GPU or crashing during periods of high CPU usage can usually be traced to GPU selection, drivers, background processes, game files, or system resource limits.
Start by forcing the game to use the high-performance GPU, then update your graphics driver and verify the game files. These steps are faster and safer than immediately reinstalling the entire game.
