Unusual timing issues after GPU upgrade
Unusual timing issues after GPU upgrade
Yesterday I upgraded my GPU from a GTX 1080 Ti to an RX 6700 XT. Before installing the card, I ran DDU for AMD and NVIDIA just to ensure clean drivers. Once the drivers were installed and configured to my settings, I started observing that frame time was quite inconsistent, not clearly linked to any specific cause. Anyone know what typically causes these frame time problems? The games I tested were Battlefield V, Battlefront II, Asphalt 9, and Geometry Dash. All of them had frame time issues. Battlefront II performed poorly, while Geometry Dash was the smoothest. However, since Geometry Dash is a lightweight game, it suggests something else might be at play. I also have SAM enabled, but I haven’t tested it off yet. Based on my quick check in BF5, it didn’t seem to be the issue. I’m running an R7 3700 XT with 32GB DDR4 3600 CL16 RAM on an MSI X570 MGPIO gaming motherboard. Another factor I considered but haven’t tested is that my Windows installation is heavily modified and the GUI has been altered. I didn’t encounter any problems with the 1080 Ti, but AMD might behave differently. I plan to reinstall Windows later after backing up my data just in case. What do you think is the real cause?
i can try that later. the gpu and the motherboard are pcie 4.0 capable and i have it in the correct spot. shouldnt it negotiate the speed automatically? i know thats an issue with risers but i dont use one.
PCIe supports various C states and adjusts its primary version and bus length during POST. These states often switch to lower versions to conserve energy, especially with PCIe 4.0 being power-intensive. If you haven’t confirmed the card is running PCIe 4.0 16x via tools like GPU-Z, it might be misnegotiating or encountering a C-state issue. C-states can also be turned off, though that’s rarely my first test. For me, hardware specs matter more than drivers—compared to a 1080ti versus a 6700 XT, performance differences are more about the chipset than software. I’ve seen multiple Windows setups run all three GPU drivers smoothly on my main rig, even achieving ultra-low latency for 4K at 240Hz.
I’ve run a lot of tests to identify the issue. I spent around four hours trying to figure it out, but my RX 6700 XT isn’t reaching its rated clock speeds. When playing games like Star Wars Battlefield II, the GPU only hits 1000 MHz instead of the expected 2600–2700. Adjusting the clock speeds in the AMD control panel improves performance slightly, but it’s still not ideal. I notice performance drops to low hundreds of MHz when I manually set the clocks. Framerate problems appear during open scenes, which my 1080 Ti doesn’t have. My friend with a 6600 XT tested his PC and found no issues there. I’m getting closer, but I really need your help.
Do you have the most recent chipset drivers? If not, install them first. Then configure the computer for high performance and check if that resolves the issue. Also, please share your Windows version, as I’d like to determine if it’s a Windows-related problem. I reviewed your previous messages but couldn’t locate your exact Windows release.
I’m pretty sure I have the newest chipset drivers installed. It doesn’t seem like the problem is with Windows because my friends’ computers also worked without issues, even though they’re using the latest version of Windows 11. Still, I plan to reinstall the driver just in case. I’ve already tried everything and checked online, but no one has given a clear answer. If the card functions on other systems but not on mine, it probably points to a motherboard compatibility issue. It’s not the usual fix, but I’m starting to think the platform might be the culprit since all other factors have been addressed. Am I missing something?
Your assumption seems to rely on a specific setup. Without a fresh Windows installation and a functioning GPU on another machine, it’s hard to confirm. You mentioned modifications, but I’m unsure if all manufacturer drivers are installed. The only factor you’ve dismissed is the GPU working, which is helpful for troubleshooting. Hardware issues are rare compared to software misconfigurations or bugs. For instance, AMD CPUs sometimes face fTPM stuttering with certain UEFI and chipset setups—issues that usually resolve with software updates. Modern systems are complex, so problems can arise unexpectedly, but permanent hardware failure is unlikely. Today’s operating systems and drivers generally handle compatibility better, though performance can still vary.
