I'm trying to get a specific high-end game running optimally, and I've been focusing on optimizing the graphics pipeline using Vulkan. I recently upgraded my setup, and I'm running into some weird frame rate drops, especially when the scene gets complex. I'm using the latest drivers and have followed all the guides for the Vegas build, but the performance seems inconsistent. Has anyone else running this specific combination (Vulkan, Vegas hardware, and Brazilian power grids) encountered similar stability problems? Any advice on optimizing the power settings or checking for specific driver conflicts would be greatly appreciated.

Have you checked your CPU throttling limits? Sometimes the power draw from the GPU causes the CPU to limit itself, especially with fluctuating power input.

Brazilian power grids are notorious. I suggest investing in a high-quality UPS (Uninterruptible Power Supply) with voltage stabilization. Fluctuations are probably the biggest culprit, not the software.

Vulkan is complex. Are you sure the issue isn't related to the specific render pass setup? Maybe try profiling with RenderDoc to pinpoint the bottleneck.

Short. Check cables.

I ran into this exact issue last month. It wasn't the power, but a conflict with an older peripheral driver (specifically my RGB controller). Update everything, even if it seems unrelated.

Did you try optimizing the power profile in Windows? Sometimes 'Balanced' mode is too aggressive and causes dips when the GPU demands peak power.

The Vegas build itself might have specific BIOS limitations regarding PCIe slot power delivery. Check your motherboard manual for recommended power draw limits for the GPU.

I found that enabling specific power management features in the BIOS, related to PCIe link state power management, made a huge difference. It stabilized the frame timing.

How are you monitoring the power draw? Just relying on frame rate drops is insufficient. Use hardware monitoring tools to see if the GPU is hitting its thermal or power limit.

I think the issue might be the driver version itself. Sometimes the bleeding edge drivers introduce instability. Try rolling back to a stable, slightly older version of the Vulkan SDK.

I agree with the UPS suggestion. I live in a region with terrible voltage spikes, and my performance only stabilizes when I run it through a dedicated voltage regulator unit. It's a must-have investment.

Could it be related to the game's specific usage of compute shaders? Some high-end games push Vulkan compute pipelines in ways that older hardware/drivers struggle with.

My experience suggests that the combination of high-demand Vulkan rendering and unstable power input (like in Brazil) creates transient voltage dips that the GPU struggles to recover from quickly, resulting in noticeable stuttering.

What about the OS? Are you running a fresh install of Windows, or is there a lot of background telemetry/services running that might be stealing cycles?

I suspect the issue is the interaction between the Vegas chipset and the specific power delivery requirements of modern high-end GPUs under Vulkan load. Check for BIOS updates specifically addressing power efficiency.

I also had trouble with this. It turned out to be a simple conflict with my network adapter's power saving mode. Disabling its power management fixed the stuttering immediately.

Have you checked if any background anti-virus or optimization software is hooking into the graphics API calls? They often cause unpredictable performance hits.

If all else fails, try limiting the frame rate cap to 60 FPS using an external tool like RivaTuner. Sometimes letting the GPU run too aggressively without proper power management causes the instability.
