 Windows Search - Game Mode Settings - Game Mode

Game Mode is a setting that provides more resources for games by reducing background processes and unnecessary system activity.

Additionally, Windows Update does not install drivers or send notifications.

Back in the Windows 10 days, when it first came out, it was a function that touched all the CPU and GPU schedulers, so performance could be degraded.

It was a feature that could be, but it's not anymore. Now there's not much difference whether you turn it on or off.

Doing a lot of things other than Lost Ark (watching YouTube..etc) -Turn off

Typical user -Turn on 

Windows Search - Edit Power Management Options - Power Options - High Performance 

If you haven't touched anything in the high-performance advanced settings, Processor Power Management - Maximum Processor State

is set to 100. If it is not set to 100, please set it.

If you set it to less than 100, the CPU boost clock will not work properly.

Maximum processor state- 100%

Windows Search - Graphics Settings - Change Default Graphics Settings

Hardware acceleration setting is a function that reduces the burden on the CPU to the GPU, but

This setting actually causes micro stuttering. Turning on this feature will increase the frame rate on computers where the GPU is idle.

It rises slightly, but sometimes the copy engine is activated and the copy process is transferred from system memory to graphics memory.

The usage rate of the engine peaks and causes stuttering.

And turning this on slows down loading in Lost Ark. Turn it on if you're curious.

This option only appears when G-Sync (FreeSync) is enabled. Turn it on if you want to use G-Sync!

Windows 8 and above are designed to always go through dwm when playing in windowed mode, so triple buffering is forcibly applied.It cannot be completely resolved.

However, using this function will release the frame limit to some extent in windowed mode. Whether vertical sync and triple buffering are released or otherI'm not sure what settings are changed to. The official Windows documentation does not explain it properly. I will modify it when I find it. . .

However, you must set the default refresh rate to the highest available value in the Nvidia settings.

Turning on this feature changes the game to the filp model, allowing you to use G-Sync even in windowed mode.

It has higher performance, lower frame delay, and better memory management than the existing legacy model.

However, there is a conflict with Lost Ark's own vertical sync, so you must disable vertical sync in the Nvidia control panel (excluding G-Sync).

Otherwise, performance will decrease.

1. Hardware acceleration schedule -Turn off (recommended)

3. Optimization for windowed games -Turn on (recommended)

Windows Search - Core Isolation

This option is not necessary for general users.

Turning it off in games like Lost Ark that use the CPU well will increase the frame rate.

You can skip this if your CPU does not support virtualization or if you have disabled virtualization in CMOS.

You can skip it if you can't search and use it.

Memory Integrity -Turn off

Virtual Machine Platform -Uncheck

Windows Search - Device Manager - Sound, video and game controllers and Audio inputs and outputs

Turning off HDMI-related high definition audio devices has been shown to reduce stuttering in most systems.

There is a definite feeling in the village. Try it in Bern and Kalinarie

All unused audio devices -Disable

Nvidia Control Panel - Manage 3D Settings - Global Settings

Since global settings affect all games, only one setting is set.

Increasing the shader cache size is effective in poorly optimized games, so set it.

In fact, you can't use them all even if you leave them at the default value.

Shader Cache Size -10GB (recommended)

Don't touch the rest.

Nvidia Control Panel - Manage 3D Settings - Program Settings - Lost Ark

Lost Ark default installation path:C:Program Files(x86)/Smilegate/Games/LOSTARK/Binaries/Win64

Do not touch the parts that follow the global settings, and only modify what is necessary.

Turning off vertical sync helps reduce stuttering and is a feature designed to prevent tearing (screen tearing).

Quarter-view games like Lost Ark don't have tearing, but they are less common than other first-person games, and vertical sync

You lose more than you gain by turning it on.

Low latency mode reduces input lag by arbitrarily limiting GPU usage, so the GPU is constantly used at 90 percent or more.

Frame rate drops on old computers.

Maximum frame rate works properly in full screen, but in windowed mode, it exceeds your monitor's refresh rate.

It cannot be limited to the top. Even if you limit it to 160FPS on a 144 monitor, it will be limited to 144.

Vertical Sync -Turn off

Preferred refresh rate- Highest available

Low Latency Mode -Turn off (for those who value every frame)

Power management mode -Prefer maximum performance

Maximum frame rate -59(60hz), 142(144hz), 162(165hz), 235(240hz)

It works normally even in windowed mode, and the frame rate is the most stable and clean.

I also use G-Sync enabled in windowed mode.

Since it is a function that adjusts the refresh rate according to the game frame rate, the mouse appears to be cut off when the frame rate drops.

If you feel uncomfortable or have any problems, please do not use G-Sync.

G-Sync activation -Enable for windowed and full screen mode

Monitor technology- G-Sync compatible

Vertical Sync -Turn on (stable frame rate while tolerating some stuttering)

Low Latency Mode -Turn off (when you want to get the maximum frame rate)

Power management mode -Prefer maximum performance

Maximum frame rate- 58(60hz), 142(144hz), 162(165hz), 235(240hz)

Shadows and indirect shadows have a big impact on performance.

Adjust and use these two settings as much as possible.

Shadow -High~Medium (recommended)

Indirect shadow -Low~Off (recommended)

This is how hard I have optimized to play Lost Ark.

Caseroth Raid Echidna is coming out soon, so let's run in a pleasant environment!

As an aside, I've been putting off posting an estimate..

It's good to see this article together

I'll be back soon!
