Do Antivirus & Background Security Tools Reduce Gaming FPS?
How Antivirus Software Works
Basically, antivirus softwares are designed to protect our systems from every kind of a virus. Its functionality depends upon many factors. Mostly the antivirus softwares work in the background during gameplay. They constantly monitor our system’s files, processing, network activity, and running softwares for viruses. Even when we are watching a video, playing a game, doing any other work, the antivirus tools are running in the background to give a secured environment. These softwares scan the files that are being accessed at the real time.
They check the memory usage, inspect the network packets, and all the other currently running checks to ensure that our system is secured. Modern Battlefield and Championship games constantly load textures, shadows, assets, costumes, and many other such additions which can trigger antivirus scans repeatedly. This background behavior consumes the CPU cycles, RAM, GPU rendering, and sometime cause the system overheating. On low-end and mid-range systems, this extra usage interferes with the gaming performance and causes the system to lag, microstutter, frame pacing issues, delayed loading time, and many others.
Real-Time Protection vs Gaming Performance
Real-time protection is the main feature of almost all the antivirus softwares. Due to this feature, an antivirus software constantly scans every single process opened or modified or running in the background for any security threat. And during game, this protection means to scan every game file, patch update, cache file, and anything instantly. Fast-paced games heavily rely on smooth asset streaming, real-time screen scanning, which introduces small-small delays.
| Antivirus Tool Type | Real-Time Scan Load | CPU Usage | RAM Usage | Disk Activity | Network Monitoring | Game Mode Support | FPS Impact Level |
|---|---|---|---|---|---|---|---|
| Windows Defender | Medium | Low | Low | Low | Medium | Yes | Low |
| Lightweight AV | Low | Low | Low | Low | Low | Yes | Very Low |
| Full Security Suite | High | Medium | Medium | Medium | High | Partial | Medium |
| Free Antivirus | Medium | Medium | Medium | Medium | Low | Limited | Medium |
| Enterprise Security | High | High | High | High | High | No | High |
| AV with VPN | High | Medium | Medium | Medium | High | Partial | Medium |
| AV with Cleaner Tools | Medium | Medium | Medium | Medium | Low | Partial | Medium |
| Old AV Software | High | High | High | High | Medium | No | High |
| Optimized Gaming AV | Low | Low | Low | Low | Medium | Yes | Very Low |
| Background Scanner Only | Medium | Low | Low | Medium | Low | No | Low |
| Scheduled Scan Active | Very High | High | Medium | High | Low | No | High |
| Cloud-Based AV | Low | Low | Low | Low | Medium | Yes | Very Low |
These delays not every time lower the performance, but also affect the frame stability. Competitive gamers often notice this more than the average gamer. Because of their high-end system, everything is quite visible. Some antivirus tools are designed to optimize the gaming activities and reduce the scanning instantly, but this causes a security threat. So do check this before installing any game.
CPU Usage Impact of Security Tools on FPS
Antivirus softwares rely on both the hardware and the software, and in the hardware, they mostly rely on the CPU. For scanning every single file, threat detection, behavioral analysis, they depend on CPU. During the gaming and heavy processes, the CPU is already busy, but these checks make the CPU to touch its edges. CPU is designed for handling the physical calculations, AI logic, draw calls, and many other processes. So that’s why it is mostly used for this process.
When a software security tools uses additional CPU threads, it mostly creates the contention, especially on quad-core or older processors. This results in bottlenecks where the GPU waits for the data rendering and overall lowers the FPS. Games that are CPU heavy, such as championship games, are more affected than the normal offline games. On high core counts, the impact is smaller, but still measurable and quite visible. And the CPU spikes from background scans causes the sudden FPS drop during these intense gameplay moments.
RAM and Disk Access Conflicts While Gaming
Moderate antivirus softwares load the signature databases and other monitoring methodologies into the system memory, and at the same time, the game running also requires a lot of memory to run the processes, fully engages the CPU as well as GPU. It has many of stuff to do like store textures, maps, assets, costumes, usernames, and many other details. So if our system is having limited RAM, it would definitely lag, and antivirus tool pushes the memory usage at higher, forcing the system to delay the game process as we have given the priorities to the antivirus softwares, that’s why.
Diff SSD conflicts, this is another issue, especially on HDDs, especially when both the antivirus software and the game want to access the same file simultaneously. The load time increases, causes stutters and screen lag. SSDs reduce this problem but cannot fully eliminate it. Games with the frequent streaming are more sensitive to this background interference than the offline games.
Safe Ways to Reduce FPS Loss Without Disabling Security
As we know that disabling antivirus software is completely risky and I cannot prefer that, and it is also not recommended by the experts. Instead of it, using a safer optimization is the best option. Adding the game folders on which we fully rely and we are completely sure that they are from the trusted sources, then we can add those games to the exclusion list and prevent unnecessary scanning.
Scheduling the full system scan outside the gaming hours is another way to bypass this scanning. Enable the built-in game mode features that help to reduce the background activity. Keeping the antivirus software update ensures the better optimization, better security, and fixes the bugs. These are the steps which allows the gamers to ensure the security while getting a good gameplay gaming experience and having the highly optimized systems.
Key Ways Antivirus Affects Gaming FPS (List Section)
-
Real-time file scanning during asset loading
-
CPU thread usage causing bottlenecks
-
RAM consumption leading to memory pressure
-
Disk access conflicts during gameplay
-
Background scheduled scans triggering stutters
-
Network packet inspection increasing latency
-
Extra bundled features running silently
-
Poorly optimized Game Mode implementations
-
Conflicts with anti-cheat systems in games
When Antivirus Has Little to No FPS Impact
On high-end gaming systems, a fully professionally designed system with a lot of CPU resources, plenty of RAM, fast NVMe SSDs, the impact of the antivirus software is minimal because there are enough spare resources available, and which helps the antivirus software to handle the checks more efficiently and will not interrupt with the currently running softwares that can be a game. Well-optimized antivirus software also reduces the resource usage.
So the result is that a good gaming system with a good optimized software helps us to maintain the higher FPS, but if we are having a mid-range system, then an optimized antivirus software can also ensure a high-profile security as well as the optimized game. And it is obvious that on high-end strong systems, background scans still affect the frame stability, but it is mostly not unnoticeable. So optimize your system as well as the antivirus software.
Final Verdict
It is obvious that antivirus software’s, background running programs, running applications, software, games, all of these reduce FPS. But the impact depends on the specs of the system and the software used and the game type running. On a low-end system, the effect is more noticeable. On modern high-end gaming systems, the impact is usually low but still noticeable. Completely disabling any antivirus software is not recommended.
Smart configuration and keeping all the things settled down help us to maintain a secured and highly optimized system. The balance must be maintained by the gamer between the hardware of the system, antivirus software, and the currently running program and he/she must understand how antivirus software interacts with the games, which allows you to optimize the game without sacrificing any security threat.
