谁能说出以下示例的问题是什么？

它每秒生成 65 帧而不是 300 帧。

#define WIN32_LEAN_AND_MEAN

#include <Windows.h>

#include <Thread>
#include <Chrono>
#include <String>

int main(int argc, const char* argv[]) {

    using namespace std::chrono_literals;

    constexpr unsigned short FPS_Limit = 300;

    std::chrono::duration<double, std::ratio<1, FPS_Limit>> FrameDelay = std::chrono::duration<double, std::ratio<1, FPS_Limit>>(1.0f);

    unsigned int FPS = 0;

    std::chrono::steady_clock SecondTimer;
    std::chrono::steady_clock ProcessTimer;

    std::chrono::steady_clock::time_point TpS = SecondTimer.now();
    std::chrono::steady_clock::time_point TpP = ProcessTimer.now();

    while (true) {

        // ...

        // Count FPS

        FPS++;

        if ((TpS + (SecondTimer.now() - TpS)) > (TpS + 1s)) {

            OutputDebugString(std::to_string(FPS).c_str()); OutputDebugString("\n");

            FPS …
